Anyone looking for evidence of changes to the internal design of the next iPhone has been busy lately. Several leaks in recent days have piled on proof of a dual LED flash, sapphire home button, and a gold iPhone 5S in the works. Now Nowhereelse.fr shows off the back panel of the iPhone 5S with several updates over the current model iPhone.
Most interesting are the changes centering around the home button, which can be clearly seen in the photo above. Assuming the part is the real deal, Apple has changed the shape of the home button backplate, also moving the mounting point down on one side. The new part could possibly be designed to retain a fingerprint sensor, and reports have indicated the iPhone 5S will feature a convex sapphire home button.
