iPhone 3G

                       iPhone 3G History:

This article is about the second generation iPhone. For the third generation iPhone with a similar name, see iPhone 3G

The iPhone 3G is a smartphone designed and marketed by Apple Inc.; it is the second generation of iPhone,  iPhone was introduced on June 9, 2008,  at the Moscone Center in San Francisco, United States.

The iPhone 3G is internally similar to its predecessor, but included several new hardware features, such as GPS, 3G data and tri-bandUMTS/HSDPA. The device was originally loaded with the concurrently launched iPhone OS 2.0. In addition to other features (including push email and turn-by-turn navigation), this new operating system introduced the App Store—Apple's new distribution platform for third-party applications.

History: 

On July 11, 2008, Apple released the iPhone 3G across twenty-two countries in two storage options, 8GB and 16GB. The 16GB model was produced in either black or white.

Following the release of the successor iPhone 3GS model one year later, the iPhone 3G remained on sale but became Apple's budget phone offer, with its price cut in half. This $99 iPhone 3G required a two-year contract and was available only in black and with 8 GB of storage, but came bundled with the then-new iPhone OS 3.0 firmware.^[13] On June 7, 2010, the iPhone 3G was finally discontinued, and replaced as Apple's budget phone by an 8GB iPhone 3GS selling for the same price of $99 with a 2-year contract.

Software

The iPhone 3G came preloaded with the latest version of iPhone OS, and continued to receive updates to its software for over two years, with major iterations released on an annual basis. However, the phone had access to a decreasing proportion of new features with each update as its hardware became superseded by later models.

When it was launched, the iPhone 3G came preloaded with iPhone OS 2.0. This introduced the App Store, Microsoft Exchange ActiveSync support, Apple’s MobileMe service, and push email support, along with other new features and bug fixes.

In June 2009, iPhone 3G users received the iPhone OS 3.0 software update, which introduced the long-awaited MMS feature, copy and paste, landscape support for more applications, Bluetooth stereo support, and other improvements.

In June 2010, Apple released the iOS 4.0 software update. Unlike its successor models, the iPhone 3G does not support prominent features of iOS 4.0 such as multitasking, the ability to set a home screen wallpaper, or Bluetooth keyboard support. However, it does provide access to a unified mailbox feature, homescreen folders to better organize apps, playlist creation, and other enhancements. This update was widely criticized for slow performance on iPhone 3G, though September 2010's iOS 4.1 release resolved this problem. However, unlike more modern iOS devices, this update again does not provide iPhone 3G owners with access to important features, in this case the Game Center application.
