Apple today announced the iPhone 5. The device is said to be built entirely out of glass and aluminum, and is 18 percent thinner than the iPhone 4S at 7.6mm. One of its signature features though is a larger display, measuring 4 inches with a resolution of 1136x640. To accommodate the change Apple is updating all of its apps; any third-party apps that haven't been updated will display in the center of the screen. The display also uses a full sRGB color gamut, and should have 44 percent more color saturation.
