Apple.Pro publishes an unverified image of what claims to be the back cover of the iPhone 5. The shell is white with 2 distinct holes in it. One for the camera, and the other presumably for the camera flash. Apple.Pro can't verify the authenticity of the image.
The image comes a week after the revelation of a iPhone 5 case which also had an extra hole that was believed to be for the camera flash. That case has since been removed from the original vendor site.
