The iPhone 5 was unveiled in the fall of 2012. It's 20 percent lighter and 18 percent thinner than the iPhone 4S but has a larger screen, a more powerful 4G LTE modem and a better camera. The phone also comes with a new, faster processor called the Apple A6 and is made entirely of glass and aluminum.
