M.I.C. Gadget reveals that an iPhone 5 prototype had recently gone missing from the Shenzhen district. “This should explain why we are seeing a whole lot of iPhone 5 cases in China today”, the publication concludes.

Much like the widely publicized iPhone 4 prototype that had gone missing at a German beer bar in California, the missing handset was camouflaged in an iPhone 4-like case (strange because the teardrop phone is wider and taller). Inside: A test model with a finalized iPhone 5 chassis sporting the teardrop design. The publication then builds on this tip by speculating that the device houses “slightly modified iPhone 4 electronics” plus the A4 chip “and even the same amount of memory”.

If this is true, then the tear drop iPhone may be the low end device, and the one inside the iPhone 4 case might be the high end.
