iPhone 3G
The iPhone 3G is the second generation of iPhone. It was the successor to the original iPhone, and is succeeded by the iPhone 3GS. 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.[11] Nevertheless, the 3G featured several improvements over the original. It supported Assisted GPS, 3G data and Quad-band UMTS/HSDPA.
The iPhone 3G runs Apple’s 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 user’s 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. It is no longer supported.
