It is the second generation of i Phone, and was introduced on June 9, 2008, at the WWDC 2008 at the Moscone Center in San Francisco, United States.
The i Phone 3G is internally similar to its predecessor, but included several new hardware features, such as GPS, 3G data and tri-band UMTS/HSDPA.
Would really Like some feedback as I am pretty confused by it all.The device was originally loaded with the concurrently launched i Phone 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.It was succeeded as Apple's flagship smartphone in 2010 by the i Phone 4; however, the 3GS continued in production until September 2012 when the i Phone 5 was announced.The i Phone 3GS was made available for pre-order on June 7, 2009 and released on June 19 in the United States, Canada, and 7 European countries, and on June 26 in Australia and the United Kingdom.
