Back in January, a handful of photos of what was alleged to be the fifth-generation black iPad's rear shell surfaced, showing how the device would take design cues from the iPad mini to offer a smaller form factor with narrower side bezels and more rounded rear edges. An additional photo appeared in late April, but otherwise leaks of the device's rear shell have been scarce. A variety of cases designed to fit the expected iPad 5 form factor have also been appearing in recent months.
