Purported design schematics for the iPhone 5 confirm an opening for a 4" display

Back-of-the-napkin calculations from the engineering blueprint return about 7mm taller and slightly wider front panel part than what we have now, which is not much at all, and certainly preferable than increasing the width too much and messing up with one-handed operation.

CEO Tim Cook said yesterday they will double-down on secrecy about Apple's upcoming products, which might have something to do with the current leaks, or it could just be one of the many prototypes and even an elaborate decoy and Apple unveils something totally out of whack - these schematics look rather legit, though.
