iPhone 5 prototypes seen in the wild?

It seems that a source from Foxconn has delivered some information concerning Apple's fifth-generation iPhone, where said smartphone is about to launch into normal mass production stages – assuming there are still enough parts to go around. Where design is concerned, the iPhone 5 is widely expected to look pretty similar to the iPhone 4, save for the difference in materials and screen size. A flat metal back is most likely although there are rumors of a curved back, made out of unspecified material (but definitely not Kryptonite).
