The iPhone 5 is a touchscreen smartphone designed by Apple in the US. It is the sixth generation of iPhone (previous version was iPhone 4S). The phone is a thinner and lighter and introduces a higher-resolution 4-inch screen (16:9 widescreen aspect ratio). The phone also includes a newly designed ARM processor (version 7) called Apple A6, the phone shipped with iOS 6 (Apples own operating system) and the handset also includes support for LTE.
The device has some major improvements over the iPhone 4S, the most important is the new 4" screen size. Apple has been improving each hardware and software feature of the phone to offer the best experience possible, instead of filling the handset new features that consumers don't use or don't understand
