IPhone 3G

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

The iPhone 3G was internally similar to its predecessor, but included several new hardware features, such as Assisted GPS, 3G data and tri-band UMTS/HSDPA. The device also benefited from software improvements introduced with iPhone OS 2.0, which was launched at the same time. As well as other features (including Push email and turn-by-turn navigation), this new operating system introduced the App StoreApple's new distribution platform for third-party applications.

At least, Saw Yan Naung had used the phone since October 2008 and some of them had changed their interfaces until September 2009.
