Those blurry images of mysterious iPhone 5 prototypes were mostly spot on. Apple's 6th-generation handset is indeed slimmer and taller than its predecessor. Sheathed in an aluminum and glass exterior, the new iPhone is 7.6 millimeters thick, out-slimming the Huawei Ascend P1 by 0.09 millimeters--not that you'd notice. The iPhone 5 weighs 112 grams (3.95 ounces) and is 18% thinner and 20% lighter than the iPhone 4S. One way Apple trimmed the fat was by embedding touch electrodes between the Retina display pixels, resulting in a 30% thinner display. The iPhone 5 also uses a nano-SIM card, which Apple says is 44% smaller than a micro-SIM. However, the new iPhone is nearly 9 millimeters longer than its predecessor.
