Chinese outfit WeiBusi on Tuesday posted a photo of what's purported to be the back of the next iPhone, which many are tentatively referring to as the iPhone 4S. The white shell matches up with that of a very early case design and, in keeping with recently mentioned parts, points to a moved camera flash that sits opposite the camera itself. The design superficially resembles that of an iPhone 4, although that couldn't be verified without the rest of the body.
