iPhone (/ËaÉªfoÊn/ EYE-fohn) is a line of smartphones designed and marketed by Apple Inc. They run Apple's iOS mobile operating system. The first generation iPhone was released on June 29, 2007; the most recent iPhone model is the iPhone 7, which was unveiled at a special event on September 7, 2016. The user interface is built around the device's multi-touch screen, including a virtual keyboard.
Such applications appeared even before the release of iPhone; the first being OneTrip, a program meant to keep track of the user's shopping list. On June 29, 2007, Apple released version 7.3 of iTunes to coincide with the release of iPhone. This release contains support for iPhone service activation and syncing.
