The iPhone 5, at only 7.6 mm thin and 112 grams, is 18 per cent thinner and 20 per cent lighter than the iPhone 4S. It is precisely engineered with a diamond-cut bevelled edge around the display. The 8-megapixel camera is crafted of sapphire crystal glass, and the new 4" Retina display provides a brilliant 1136 x 640 pixel resolution.
