ABSTRACT
The iPhone was first released in June 2007 and has since had two major revisions: the 3G and the 3GS. In early 2008, Apple released an official iPhone SDK which enabled developers to create native applications for the device. A physical device is not required for most of development as a software implemented iPhone Simulator is provided with the SDK. Only members of the paid developer program are able to test their creations on a physical device and subsequently submit them to the App Store for distribution.
