9to5mac reports on a video hands-on that supposedly shows a new unibody backplate for the 2012 iPhone. Take this with a grain of salt, Apple could be producing fake prototypes to throw people off and people commonly fake this sort of thing, but that said the video looks legitimate.

The video shows a backplate for the new iPhone that incorporates the stainless steel band and backplate found in previous iPhones into one part. The video also displays what appears to be a partially metal back, which seems dubious at best.
