This is said to be part of the next iPhone. The backside of the case, to be exact.
It’s not clear whether these images are real, but it looks like it has an aluminum plate on the backside. This is more similar to the iPad design. Perhaps too many dropped iPhone 4 and iPhone 4S units made Apple consider a change in materials.
Even then, it’s important not to get too caught up in rumor-type posts. This is just an image that a parts supplier sent to a website.
What do you think?
