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.
The phone was designed for Apple by Hartmut Esslinger, an influential designer who helped make the Apple IIc computer (Apple's first portable computer) and later founded Frogdesign. The 1983 iPhone certainly fits in with Esslinger's other designs for Apple.
