iPhone 5 May Have Metal Back and Sub-4-inch Display : Reports

The still-unacknowledged iPhone 5, expected to make its debut in October, is now expected to sport a metal back instead of glass, and its screen size will not exceed 4 inches, contrary to earlier reports.Instead, the next iPhone will have a display size between 3.5 and 3.7 inches -- the current model has a 3.5-inch display -- and may also have a thinner bezel along the sides of the device to make the screen look larger than it actually is. 

Other than those changes, the next iPhone is not expected to be remarkably different from the iPhone 4, sources inside Apple's supply chain have reportedly told Taiwan-based DigiTimes. Shrinking Screens Suggestions the next iPhone would have a 4-inch screen have been circulating for some time. In February, DigiTimes claimed the iPhone 5 would have a 4-inch screen, and a similar report followed a month later in the China Times. DigiTimes is apparently backing off its original report, and now says the next iPhone's display will not be much larger than the usual 3.5 inches.
