Parts hint at rounded edges
New images depict what are said to be black and white front cover panels for a 4.7-inch iPhone 6. Compared with the iPhone 5s, the panels aren't much larger in size, and are generally similar in design. They do have what appear to be differently-placed camera holes however, as well as rounded edges, which may be intended to better fit the iPad mini-style back the phone is expected to have. The inconsistency in the camera holes may theoretically be connected to them coming from different development phases.
Still missing from leaks is a cover for the 5.5-inch iPhone. That device is believed to have suffered production delays, however, which while corrected may mean that parts are only just beginning to roll off of assembly lines. Both products should ship this fall.
