The iPhone is a line of smartphones designed and marketed by Apple Inc. All generations of the iPhone use Apple’s iOS mobile operating system software. The first-generation iPhone was released on June 29, 2007, and multiple new hardware iterations with new iOS releases have been released since.
The most recent iPhones are the iPhone 6s and iPhone 6s Plus, which were unveiled at a special event on September 9, 2015.
All iPhones have a nearly identical design, with a few generations offering minor changes.
