The iPhone 5 is a touchscreen-based smartphone developed by Apple Inc, the sixth generation of the iPhone. It was announced on September 12, 2012, and was released on September 21. It has a larger 4-inch screen and a smaller eight-pin dock connector than its predecessor, and is lighter, thinner, and contains the Apple A6 processor.Runs the latest iOS 6.  It is the first iPhone that supports LTE (4G) or has a screen with a 16:9 widescreen aspect ratio.
The reception to the iPhone was primarily positive as many reviewers praised the hardware improvements such as the larger and higher resolution screen and improved internal components. However, many negatively received the new "Maps" application as it is reported to contain many serious errors. This will be something fixable in the coming updates of iOS 6.
