Quality photos on iPhone 5 were published on the web site 9to5mac.com. The design has been updated but not totally different from the current model currently 4S.
Most of the back of the iPhone 5 is made entirely of metal, installed a new connector for docking station. The chassis is the usual “unibody” performance that makes the Apple devices thinner and healthier. The back of the smartphone features a gradient of color in the top and bottom color is more intense.
Dock connector is sort of mini USB port, but will not pass without a special cable from Apple. The microphone seems to have moved between the rear camera and LED flash. The display seems to be greater with 4-inch diagonal and a resolution of 1136 x 640, while the iPhone 4S provides 3.5-inch screen.
