Tips distinguish iPhone replica with the original

here way to check who is the original.
1. for 2G only. backcase nothing other than the iron.
2. check S / N and IMEI, which took place in backcase, cross check in the box.
3. check the settings>> general>> about
4. IPhone internal memory only. It means can not be added.
5. before buying, try to borrow the iPhone has a friend, will feel the difference when holding the iPhone replica.
6. Motion in the iPhone OS and it is definitely felt the difference.
7. there is a laptop + iTunes? plug, if not to detect, it's a replica.

code Error iTunes

If you have problems restoring, try to use DFU mode, because it has a chance to succeed in restoring.

Error 1011, 1013, 1015 when the restore is complete:
means the modem firmware could not be updated, if this error occurs when you're downgrading devices (eg: 1.1.4 to 1.1.3), this is normal. you need a program like Independence (on Macintosh) or Jailbreak 1.1.2 (on windows), to boot your device from the recovery mode, as well as complete the downgrade. if the device you have the words "need repair", and you restore, the same error persists, the possibility of permanent damage in your device. try to use DFU restore, and hope for the best.

Error 1602, 1603:
This is sort of an unknown error. but it is usually caused by a loss of connection to the Device your iTunes. usually Reboot or restart your Apple device to solve this problem, there are times where you need to reinstall iTunes, or where in some serious cases, need help Apple support. you may be lucky when the restore without entering the SIM card. (off the SIM card, reboot the device into restore mode, then try the restore once again.)

Error 1600 on OSX:
try mkdir ~ / Library / iTunes / "Device Support"
if that directory already exists, try deleting all files in it.

Error 1604:
see at here

Error 1, 2, 3, 6, or an error number below 99:
your device can not be restore mode.
try to DFU mode, and try to restore once again.

Error 9, 23
hardware problem, it is advisable to claim to Apple to request instead.


Error 1013/1014/1015

This error message occurs when you downgrade or upgrade to a different baseband than the firmware your restoring to has. This message does NOT mean the restore failed – it simply means the phone firmware does not match the baseband. Put your phone in recovery mode and then kick the phone into normal mode and out of recovery mode and it will work.

Error 6 and 10

This error message is because of a problem with your firmware – this message will occur most often because of using unsuitable boot/recovery images. Make a new custom firmware to fix this and use suitable boot images or use the standard images that came with the pwnage software.

Error 1603/1604 – 160? something

IF YOU ARE RESTORING TO A STANDARD APPLE FIRMWARE *NOT CUSTOM FIRMWARE”

This error is down to itunes not liking your USB ports on your computer. Use a different USB slot or a different computer if possible. That is the easiest fix!

IF YOU ARE RESTORING TO A CUSTOM FIRMWARE AFTER RESTORING FROM STANDARD APPLE FIRMWARE

IF you have pwned your phone once and then restored back to apple original firmware successfully and THEN tried to restore custom firmware you WILL get an error in iTunes as the apple firmware “unpawned” your phone. You have to repwn it using iPwner and then you can restore using custom firmware.

IF YOU ARE RESTORING TO CUSTOM FIRMWARE AND YOUR PHONE IS STILL PWNED

seting internet network iphone

Access Point Name (APN) is a computer protocol that typically allows a user's computer to access the internet using the mobile phone network.

On a technical level it is a configurable network identifier used by a mobile device when connecting to a GSM carrier. The carrier will then examine this identifier to determine what type of network connection should be created, for example: what IP addresses should be assigned to the wireless device, what security methods should be used, and/or how should it be connected to some private customer network.

More specifically, the Access point name (APN) identifies an IP packet data network (PDN), that a mobile data user wants to communicate with. In addition to identifying a PDN, an APN may also be used to define the type of service, (eg connection to wireless application protocol (WAP) server, multimedia messaging service (MMS)), that is provided by the PDN. APN is used in 3GPP data access networks, eg general packet radio service (GPRS), evolved packet core (EPC).

Apple iPhone 4G specification

You can't make a phone that everyone loves and Apple is not even trying. Much like any other iPhone so far, the iPhone 4 is a phone that everybody loves AND hates.
Apple’s latest is always the greatest – you have to give them that. Sometimes it seems they put less effort into making it than in letting people know they did. But with the Apple iPhone 4, they were obviously hard at work. The 4th generation iPhone has an all new look, new feel and plenty of new skill. We already caught a glimpse of the iOS4. But there’s much more: a 1GHz chip, two cameras, HD video and of course the Retina display – the highest-res screen we’ve seen so far on a GSM phone.




 

 

 








  





Surely there are still enough blank spots on the feature list but that’s Apple and its iPhone. Compromises are being made in every phone out there anyway. But the simple fact is Number 4 is the best iPhone to-date. Let’s see how good that is.

 Key features
  • Quad-band GSM and quad-band 3G support with 7.2 Mbps HSDPA and 5.76 Mbps HSUPA
  • 3.5" 16M-color LED-backlit TFT capacitive touchscreen of 640 x 960 px resolution
  • Scratch-resistant glass front and rear, with fingerprint-resistant coating
  • 1GHz Apple A4 SoC; 512MB of RAM
  • 5 MP autofocus camera with LED flash and touch focus
  • 720p video recording at 30fps
  • Wi-Fi 802.11b/g/n
  • GPS with A-GPS connectivity; digital compass
  • 16/32GB storage options
  • Accelerometer, proximity sensor and three-axis gyro sensor
  • Active noise cancellation with a dedicated secondary microphone
  • Standard 3.5 mm audio jack, stereo Bluetooth v2.1
  • Excellent audio output quality
  • Slim waistline at only 9.3mm
  • Secondary front-facing camera
  • Some degree of multitasking
  • Rich AppStore

Main disadvantages

  • Hardware design is prone to reception issues
  • MicroSIM card support only
  • No Flash support in the web browser
  • No true multitasking for all applications
  • FaceTime video calls work only over Wi-Fi
  • No file transfer over Bluetooth or USB Mass Storage mode
  • No hardware shutter key for the camera
  • No FM radio
  • No stereo speakers
  • No microSD card slot
  • No smart dialing
  • Too dependent on iTunes for loading multimedia content
  • Poor loudspeaker performance
As you can see, most of the main disadvantages are simply passed from one generation to the next but - whatever iPhone you’re coming from - the Number 4 will tick most of your boxes. Upgraders will be used to the shortcomings, and unbiased observers will have less points to complain against.
It just seems some features will be forever missing. The iPhone’s memory isn’t expandable and you can’t use the thing as an external drive (this also means that files are only transferred via iTunes, again). Bluetooth has been upgraded to cover not only for music and calls but a compatible wireless keyboard too. File transfers however are a no-go.
The lack of Flash support in the Safari browser is no surprise given the Apple-Adobe feud. Luckily there’s the good old YouTube app to partly make up for that but Flash games are still out of the question.
There is now a secondary video-call cam but the “reinvented” FaceTime video calls feature only works over Wi-Fi (for now) and between two iPhone 4’s.
As for the multitasking, this is the closest the iPhone has ever gotten but there is no true multitasking, and certainly not for all apps.
You've probably also heard of the user reports of reception issues and you're wondering how much of that is true. Well, we've checked that in detail, too.



 

All that (and a bit more) aside, the new goodies seem to merit at least some of the iPhone 4 hype. The Retina display is gorgeous. The 3.5” capacitive TFT touchscreen has four times the resolution of the older iPhones. At 640 x 960 pixels, it’s the best we’ve seen – statistically. But perhaps the most impressive too, for its actual performance.

There’s a generational leap in imaging too. The first two iPhones had a single 2MP fixed focus camera on board. Last year’s 3GS tried to make some sense with a 3-megapixel autofocus snapper. With the iPhone 4, Apple are finally beginning to look good. The primary 5-megapixel autofocus camera not only takes impressive images but shoots 720p videos too. Oh, and it has a LED flash.
Now, let’s see what else is in that tiny white retail box and check out those shiny glass panels. Let the iPhone 4 unboxing begin. (source: gsmarena)


  

all about itunes

iTunes is a free application for your Mac or PC. It organizes and plays your digital music and video on your computer. It keeps all your content in sync. And it’s a store on your computer, iPod touch, iPhone, iPad, and Apple TV that has everything you need to be entertained. Anywhere. Anytime.

iTunes lets you enjoy all your music, movies, video, and TV shows on your Mac or PC. When you want to watch or listen to something, you no longer have to look through your CDs or flip through channels — just go to your computer and open iTunes. With your entire media collection in your iTunes library, you can browse everything faster, organize it all more easily, and play anything whenever the mood strikes.









 












How do you get your music and movies from your Mac or PC to your iPhone, iPod, or iPad? iTunes does it for you. How about photos, contacts, and calendars? iTunes transfers them, too. iTunes makes it surprisingly easy to sync media from your computer to your device, and the other way around. Shop the iTunes Store directly from your iPhone, iPod touch, or iPad. You can download music, movies, and TV shows anywhere you are over a Wi-Fi network. When you’re back at your computer, connect your device. iTunes syncs what you bought on the road to your iTunes library. iTunes also wirelessly syncs your iTunes library to your Apple TV, so you can see your movies, listen to your music, and look at your photos on the big screen. (source: apple.com)

How to sync to multiple computers? Make sure you have hexedit, if not, download at here.

On the first computer
1. Open the itunes folder, usually in music / my music. After that open the iTunes music library.xml file, open it with notepad.

2. Find a library persistent id in notepad. search, record numbers on the library persistent id.

Example: <key> Library Persistent ID </ key> <string> 5639AB80882BF9AB </ string>
note the bold.
3. Close notepad. If there are changes not saved. should remain the default, so if asked to save, select no.

In the second computer
1. Open the itunes folder in the same manner as above. Copy files and itunes itunes library.xml library.itl.

2. Open itunes library.xml in the same way, note the library persistent id, and change so that the first computer.

Example: <key> Library Persistent ID </ key> <string> 084081498FE5B8CD </ string>

The one in bold, record and then change so

Example: <key> Library Persistent ID </ key> <string> 5639AB80882BF9AB </ string>

3. Open Hexedit, continue to search with the click find and type the hex, the first library persistent id (which is in bold), and change so that the two (bold and italic). Close and save.

Done, now try the sync. If successful, there is no warning that all data will be lost.

Apple iPhone 3GS specification

The Apple iPhone 3GS is probably not the next revolutionary iPhone as you might have expected it. But the performance boost, the sharper camera with video and the purportedly improved battery life certainly make of the current iPhone (3GS or whatever it is called this year) a much more balanced smartphone, one that you could probably wave in front your geeky friends more proudly. Well, you'd still get the chilling disapproving look, but at least you won't feel as embarrassed as you used to.

The truth about the iPhone is this - perhaps about 20 million people around the globe are quoted as having given in to the iPhone temptation ever since the frenzy started. Now, 2 years later, the rest of the modern world is already sick to death of hearing all about it.





















Once ground-breaking, but still as controversial and inspiring as ever, the iPhone lineup has just received its latest offspring. Meet the iPhone 3GS, where "S" can mean a lot of things, but without a doubt covers all that's needed for "Speed".

Using last year's design but boasting some extra powerful hardware, the iPhone 3GS is supposed to, and indeed is, running up to 2 times better than what Apple have offered us so far. This speed boost doesn't bring substantial new capabilities to the table. Instead it's more like the hardware catching up with what we can still call one of the most advanced and user-friendly touch user interfaces to-date (in the realm of GSM mobile phones, of course).

While the iPhone 3GS and the 3G are most obviously cut from the same cloth, you'd be glad to know that there are some differentiating factors that can perhaps be worth your cash: 
iPhone 3GS advantages over iPhone 3G:

    * A faster 600MHz CPU and double the RAM at 256MB
    * Noticeably faster performance
    * Faster network speeds of HSDPA 7.2Mbps
    * 3.2 megapixel auto focus camera with VGA@30fps video recording, touch focus with subject tracking, macro mode from as close as 10 cm
    * Double the storage space - 3GS is selling in 16GB and 32GB versions
    * Digital compass with automatic map orientation in Maps app
    * Better audio quality (as recorded and analyzed in our office)
    * Louder loudspeaker results (with performance gains primarily in music playback)
    * Purportedly better battery life
    * Oleophobic display coating supposed to make fingerprints easier to clean
    * Voice Control, speaker independent. Can be use to call a phone number, play music by song/album/artist name, shuffle music
    * Built-in support for Nike+ jogging system
    * TV-out outputs 480p instead 480i resolution
    * Text-to-speech feature called VoiceOver is included in the new Accessibility menu
    * System-wide Screen Zoom is also included in the Accessibility menu

Main disadvantages of iPhone 3GS (OS disadvantages not counted here):

    * The new iPhone 3GS lacks the same novelty factor as its predecessors - the lack of design changes is a turn-down
    * 3 megapixel camera with limited feature set hardly cuts it for a high-end device
    * There's still no flash or hardware shutter key for the camera
    * Despite the upgrade, battery life is still generally poor (2-year old iPhone 2G are still doing way better)
    * No videocalls functionality
    * No FM radio
    * No stereo speakers (or are we pushing it too far already?)

Since the iPhone 3GS is the first iPhone to come with the iPhone OS 3.0 factory preinstalled, we'll most definitely have a detailed look in this review at the changes it brings about - no matter that iPhone 2G and 3G have both received the update for free.

Where it stands today, the iPhone OS 3.0 is much more mature version of itself back in the day. Honestly, when we look at where it's at now, we can only be amazed how limited in features it was when it all started a couple of years ago.  But there's a lot to cover today, so let's not waste any more time. Join us as we go through the well known hardware and design and bear with us as we cover the iPhone OS 3.0, because it will get interesting, we promise.

Apple iPhone 3G specification

It's finally here - the iPhone 3G. No, we mean that literally. It's finally at our office and boy, are we excited! GPS, HSDPA purring under the new iPhone hood with a hefty number of software enhancements. But all them software goodies are available for the first-gen iPhone too - so is it worth the fuss? It may as well be, but we never know before we take it out for a spin.

Key features:

    * 3.5" 16M-color TFT display with a resolution of 480 x 320 pixels
    * Quad-band GSM support
    * Tri-band UMTS support with HSDPA
    * Built-in GPS receiver
    * Wi-Fi
    * 8 to 16GB of onboard storage
    * Accelerometer, proximity sensor and ambient light sensor
    * 2 megapixel camera
    * Silky smooth user interface with multi-touch user support
    * Unsurpassed web surfing experience
    * Push email with MS Exchange support
    * AppStore access for direct application download and installation
    * Redone rear
    * TV-out port

Main disadvantages:

    * No video calls over the 3G network
    * The handset wobbles on hard even surfaces
    * There are a number of messaging downers
    * Camera has no auto focus, nor video recording… nor any settings at all
    * Safari browser doesn't support Flash and Java, doesn't have a download manager
    * Bluetooth support limited to headset use only (no A2DP or file transfers)
    * No office document editor
    * No copy/paste functionality
    * You cannot sync Notes and TO-DOs
    * No memory card slot (but knowing Apple there will never be one)



Now, since we'll be heavily comparing the old and new iPhone, how about the following arrangement - the first one we'll call Number One and the newbie will be Number Two. Sorted. Wait a minute, no good? Crap, we knew it. OK then, the first one will be the iPhone 1G (as in "generation" of the device), while the new one will still be iPhone 3G (as in "generation" of the wireless network). That might sound inconsistent, but it's short and we like it this way, so before you go ballistic in the comments section, remember Number One and Number Two.





















So, back to the drill - the 3G-enabled iPhone was rumored ever since the iPhone 1G surfaced last year. Now that we have the real thing in our hands, it doesn't seem that groundbreaking anymore. Nevertheless, there are quite a few things to cover so we think reviewing it in detail is worth it. There's the updated design, the new white color (which we happen to have), the new iPhone 2.0 firmware/software/OS (call it what you will) with AppStore on board, the push email functionality and, finally, the GPS and HSDPA topping.

We will also be on the lookout for improvements in terms of audio quality, loudspeaker volume and camera image quality against the iPhone 1G. Seems like quite a workload, so let's waste no more time and get to it. Join us after this short break for more on the iPhone 3G. (source: gsmarena)

Apple iPhone 2G specifications

Cutting edge, sleek and promising, the iPhone stirred the mobile world - not bad for Apple's first go at the mobile phones market. Inspiring and provocative, the iPhone will always come to mind when a handset with full touch-based user interface is in question.

Well, since the official release of the iPhone on 29th June 2007, a lot of reviews came out, too many controversial things were said, and there we are - finally having our say about the handset. As wise people say, better later than never.

Apple is a company which specializes in developing products on the verge of science fiction. The iPod is a perfect example. Around 2001 the company decided to change portable music players as we know them, and pretty much succeeded. Much like the iPhone, the announcement of iPod generated huge amounts of hype and when it came out in October 2001 it actually lived up to almost every promise, turning out to be a total smash. As it developed, throughout the years, Apple's portable music player became the most popular mobile multimedia device and its reputation never seems to fade.





















Following the same credo of being a feature-rich, yet simple-to-use device, the iPhone will undoubtedly build a strong fan base. It will surely attract the many "if-it-ain't-shinin'-I-ain't-buyin'" customers, since the iPhone is definitely among the most beautifully crafted mobile phones we've seen.

It will be a while before we get a hands-on with the European version of the iPhone. As Apple has confirmed the device is due to hit the European market November 9th 2007 starting with UK and Germany and later on this month in France. The craved device already appeared throughout retailers in Europe ss unlocking efforts so far are managing to overcome the protection of the handset. (source at gsmarena)

Key features:

    * Stylish design
    * Scratch-proof front glass cover
    * 3.5" 16M color TFT display with a resolution of 480 x 320 pixels
    * Handset orientation sensor and proximity sensor
    * 2 megapixel camera
    * Touch-based user interface
    * Great UI graphics and animations
    * Supreme web surfing experience

Main disadvantages:

    * Camera has no auto focus or settings
    * No video recording
    * No custom ringtones allowed
    * Safari browser doesn't support Flash and Java
    * Really basic Bluetooth capabilities
    * No Office documents editor
    * No third party applications
    * No 3G support (at least the US version)





specification

Ipod and Iphone hardwares

The touchscreen is a 9 cm (3.5 in) liquid crystal display with scratch-resistant glass. The capacitive touchscreen is designed for a bare finger, or multiple fingers for multi-touch sensing. The screens on the first three generations of the iPhone have a resolution of 320 x 480 (HVGA) at 163 ppi, while the display on the iPhone 4 has a resolution of 640 x 960 at 326 ppi.

The touch and gesture features of the iPhone are based on technology originally developed by FingerWorks. Most gloves and styluses prevent the necessary electrical conductivity;  however, capacitive styli can be used with iPhone's finger-touch screen. The iPhone 3GS also features a fingerprint-resistant oleophobic coating.



 
The iPhone has a minimal hardware user interface, featuring only four or five buttons, depending on whether the volume control is counted as one button or two. The only physical menu button is situated directly below the display, and is called the "Home button" because it closes the active app and navigates to the home screen of the interface. The home button is denoted not by a house, as on many other similar devices, but a rounded square, reminiscent of the shape of icons on the home screen. A multifunction sleep/wake button is located on the top of the device. It serves as the unit's power button, and also controls phone calls. When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voicemail. Situated on the left spine are the volume adjustment controls. The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch. Directly above the volume controls is a silence button that mutes all sound when engaged. All buttons except Home were made of plastic on the original iPhone and metal on all later models. The touchscreen furnishes the remainder of the user interface.





















The display responds to three sensors. A proximity sensor deactivates the display and touchscreen when the device is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears. An ambient light sensor adjusts the display brightness which in turn saves battery power. A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode. Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations. Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input. The accelerometer can also be used to control third party apps, notably games. The iPhone 4 also includes a gyroscopic sensor, enhancing its perception of how it is moved.

A software update in January 2008  allowed the first generation iPhone to use cell tower and Wi-Fi network locations trilateration,  despite lacking GPS hardware. The iPhone 3G, 3GS and 4 employ A-GPS, and the iPhone 3GS and 4 also have a digital compass.

 


Audio and output

The bottom of the iPhone sports a speaker (left) and a microphone (right) flanking the dock connector. One loudspeaker is located above the screen as an earpiece, and another is located on the left side of the bottom of the unit, opposite a microphone on the bottom-right. The iPhone 4 includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the left. Volume controls are located on the left side of all iPhone models and as a slider in the iPod application.

The 3.5 mm TRRS connector for the headphones is located on the top left corner of the device. The headphone socket on the original iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter. Subsequent generations eliminated the issue by using a flush-mounted headphone socket. Cars equipped with an auxiliary jack allow for handsfree use of the iPhone while driving as a substitute for Bluetooth.

While the iPhone is compatible with normal headphones, Apple provides a headset with additional functionality. A multipurpose button near the microphone can be used to play or pause music, skip tracks, and answer or end phone calls without touching the iPhone. A small number of third-party headsets specifically designed for the iPhone also include the microphone and control button. The current headsets also provide volume controls, which are only compatible with more recent models. These features are achieved by a fourth ring in the audio jack that carries this extra information.

The built-in Bluetooth 2.x+EDR supports wireless earpieces and headphones, which requires the HSP profile. Stereo audio was added in the 3.0 update for hardware that supports A2DP. While non-sanctioned third-party solutions exist, the iPhone does not officially support the OBEX file transfer protocol. The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other bluetooth-enabled cell phones.

Composite or component video at up to 576i and stereo audio can be output from the dock connector using an adapter sold by Apple. iPhone 4 also supports 1024x768 VGA output via a dock adapter. The iPhone did not support voice recording until the 3.0 software update.

The iPhone features an internal rechargeable battery. Like an iPod but unlike most other mobile phones, the battery is not user-replaceable. The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet. A number of third party accessories (stereos, car chargers, even solar chargers) are also available.

Apple runs tests on preproduction units to determine battery life. Apple's website says that the battery life "is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles",  which is comparable to iPod batteries. The original iPhone's battery was stated to be capable of providing up to seven hours of video, six hours of web browsing, eight hours of talk time, 24 hours of music or up to 250 hours on standby. The iPhone 3G's battery is stated to be capable of providing up to seven hours of video, six hours of web browsing on Wi-Fi or five on 3G, ten hours of 2G talk time, or five on 3G, 24 hours of music, or 300 hours of standby. Apple claims that the 3GS can last for up to ten hours of video, nine hours of web browsing on Wi-Fi or five on 3G, twelve hours of 2G talk time, or five on 3G, 30 hours of music, or 300 hours of standby.

The battery life of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims. This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the "battery aspects" of the iPhone 3G its lowest rating of 2 out of 5 stars.

If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty. The warranty lasts one year from purchase and can be extended to two years with AppleCare. Though the battery replacement service and its pricing was not made known to buyers until the day the product was launched, it is similar to how Apple (and third parties) replace batteries for iPods. The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced. Since July 2007 third party battery replacement kits have been available  at a much lower price than Apple's own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the original iPhone has been soldered in. Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace, although replacement by any besides Apple still voids the warranty.



Camera

The iPhone and iPhone 3G feature a built-in Fixed focus 2.0 megapixel camera located on the back for still digital photos. It has no optical zoom, flash or autofocus, and does not support video recording, however jailbreaking allows users to do so. Version 2.0 of iPhone OS introduced the capability to embed location data in the pictures, producing geocoded photographs.

The iPhone 3GS has a 3.2 megapixel camera, manufactured by OmniVision, featuring autofocus, auto white balance, and auto macro (up to 10 cm). It is also capable of capturing 640x480 (VGA resolution) video at 30 frames per second, although compared to higher-end CCD based video cameras it does exhibit the rolling shutter effect. The video can then be cropped on the device itself and directly uploaded to YouTube, MobileMe, or other services

The iPhone 4 introduced a 5.0 megapixel camera (2592x1936 pixels), also located on the back, which is equipped with a backside illuminated sensor capable of capturing pictures in low-light conditions, as well as an LED flash capable of staying lit for video recording at 720p resolution, considered high-definition. In addition the iPhone 4 has a second camera on the front capable of VGA photos and SD video recording.

Storage and SIM

The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB. On September 5, 2007, Apple discontinued the 4 GB models. On February 5, 2008, Apple added a 16 GB model.  The iPhone 3G was available in 16 GB and 8 GB. The iPhone 3GS came in 16 GB and 32 GB variants and still is available in 8 GB. The iPhone 4 is available in 16 GB and 32 GB variants. All data is stored on the internal flash drive; the iPhone does not support expanded storage through a memory card slot, or the SIM card.

The SIM card sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with a paperclip or the "SIM eject tool" (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS. In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on a different mobile network. The iPhone 4 features a MicroSIM card that is located in a slot on the right side of the device.


Moisture sensors

The iPhone has moisture sensors to indicate whether water damage has affected a device. The sensors on an iPhone include a small disc which is located in the headphone jack and an area near the dock connector. The sensors are often used by Apple employees to determine whether the device qualifies for a warranty repair or replacement, and if the sensors show that the device has absorbed moisture they may determine that the device is not covered. However, the moisture sensors might be "tripped" through routine use, and if a device is worn while exercising the sweat from an owner may dampen the sensors enough to indicate water damage. On many other mobile phones from different manufacturers, the moisture sensors are located in a protected location, such as beneath the battery behind a battery cover, but the sensors on an iPhone are directly exposed to the environment. This has led to criticism of the placement of the sensors, which may also be affected by steam in a bathroom or other light environmental moisture.



Included items

All iPhone models include written documentation, and a dock connector to USB cable. The original and 3G iPhones also came with a cleaning cloth. The original iPhone included stereo headset (earbuds and a microphone) and a plastic dock to hold the unit upright while charging and syncing. The iPhone 3G includes a similar headset plus a SIM eject tool (the original model requires a paperclip). The iPhone 3GS includes the SIM eject tool and a revised headset, which adds volume buttons. The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the original model's dock. All versions include a USB power adapter, or "wall charger," which allows the iPhone to charge from an AC outlet. The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, or Peru  include an ultracompact USB power adapter. The iPhone 4 owners get free bumper case to temporarily resolve the antenna problems.

all about apple iphone and ipod

The iPhone (pronounced ) is a line of Internet and multimedia-enabled smartphones designed and marketed by Apple Inc. The first iPhone was introduced on January 9, 2007.

An iPhone functions as a camera phone, including text messaging and visual voicemail, a portable media player, and an Internet client, with e-mail, web browsing, and Wi-Fi connectivity. The user interface is built around the device's multi-touch screen, including a virtual keyboard rather than a physical one. Third-party applications are available from the App Store, which launched in mid-2008 and now has well over 300,000 "apps" approved by Apple. These apps have diverse functionalities, including games, reference, GPS navigation, social networking, security and advertising for television shows, films, and celebrities.

There are four generations of iPhone models, and they were accompanied by four major releases of iOS (formerly iPhone OS). The original iPhone established design precedents like screen size and button placement that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a compass, faster processor, and higher resolution camera, including video. The iPhone 4 has two cameras for FaceTime video calling and a higher-resolution display. It was released on June 24, 2010.






















Development of the iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens.  Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house.

Jobs unveiled the iPhone to the public on January 9, 2007 at Macworld 2007. Apple was required to file for operating permits with the FCC, but since such filings are made available to the public, the announcement came months before the iPhone had received approval. The iPhone went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide. The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six. Apple released the iPhone 3G in upwards of eighty countries and territories. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost, and 40% of users have household incomes over US$100,000. In an attempt to gain a wider market, Apple retained the 8 GB iPhone 3G at a lower price point. When Apple introduced the iPhone 4, the 3GS became the less expensive model. Apple reduced the price several times since the iPhone's release in 2007, at which time an 8 GB iPhone sold for $599. An iPhone 3GS with the same capacity now costs $99. However, these numbers are misleading, since all iPhone units sold through AT&T require a two-year contract (costing several hundred dollars), and a SIM lock.

Apple sold 6.1 million original iPhone units over five quarters. The sales has been growing steadily thereafter, by the end of fiscal year 2010, a total of 73.5 million of iPhones were sold. Sales in Q4 2008 surpassed temporarily those of RIM's BlackBerry sales of 5.2 million units, which made Apple briefly the third largest mobile phone manufacturer by revenue, after Nokia and Samsung. Approximately 6.4 million iPhones are active in the U.S. alone. While iPhone sales constitute a significant portion of Apple's revenue, some of this income is deferred.

The back of the original iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. They both are now discontinued. The iPhone 3GS was available in both colors, regardless of storage capacity. The white model was discontinued in favor of a black 8 GB low-end model. The iPhone 4 has an aluminosilicate glass front and back with a stainless steel edge that serves as the antennae. It is available in black; a white version was announced, but has as of October 2010[update] not been released.

The iPhone has garnered positive reviews from critics like David Pogue  and Walter Mossberg. The iPhone attracts users of all ages, and besides consumer use the iPhone has also been adopted for business purposes.
