An abundance of possible iPhone 5 cases found late Friday may have helped give clues as to the final design of the iPhone 5. The China-made silicone skins seen by MIC Gadget all mirror those seen earlier and support early descriptions of a major redesign of the case. All appear to have a larger surface area than the iPhone 4, tapering sides, and the ringer as well as volume controls put on opposite sides for the first time.
