The i phone 3g is the second generation of iphone It was the successor to the original phones and is succeeded by the iPhone gs . Introduced on June 9, 2008 at the WWDC 2008 at the Moscone Center, San Francisco. The 3G was very similar to its predecessor, containing the same 2 MP camera and no support for video recording, and its performance was limited by the same 128 MB eDRAM memory unit. Nevertheless, the 3G featured several improvements over the original. It supported Assisted GPS, 3G data and Tri-band UMTS/HSDPA. The iPhone 3G runs Apples iOS operating system, the same operating system used on previous iPhones, the iPad, the Apple TV, and the iPod Touch. It is primarily controlled by a users fingertips on the multi-touch display, which is sensitive to fingertip contact. Without modification, the iPhone restricts users from running any software that is not explicitly approved by Apple and distributed via its App Store. Doing so could potentially cause issues with software functionality which may not be covered under warranty.The iPhone 3G no longer receives software updates from Apple as of March 11, which was the date iOS 4.3 was released. It is no longer supported. he iPhone 3G came preloaded with the latest version of iPhone OS both to offer the newest improvements to the software and to combat efforts of jailbreaking. Over the years, the iPhone 3G has been supported by Apple with software updates. Major iterations of the software usually released yearly.At launch, in July 2008, the iPhone 3G came preloaded with iPhone OS 2.0 which introduced the App Store, Microsoft Exchange ActiveSync support, Apples Mobile Me service, and push email support, along with other new features and bug fixes as well.On June 2009, the iPhone 3G 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 as well.On June 2010, the iPhone 3G owners were issued the iOS 4.0 software update. Unlike its successor, the iPhone 3GS though, it did not receive multitasking, home screen wallpaper, or Bluetooth keyboard support. However, it still got the unified mailbox feature, folders, playlist creation, among other enhancements in iOS 4. Still despite the number of new features the update introduced, it was widely criticized for its slow performance on the device.
