If it weren't for the redesigned Home button and larger flash, the iPhone 5S and iPhone 5 would look like identical twins, at least on the outside. Take the new 5S apart, however, and the differences are more apparent -- even if only slightly so. And although it isn't the easiest phone to repair, with the right tools and a little patience, it is possible.

Cracking Open observations
Opening the phone still requires special tools: With the iPhone 5, Apple ditched the twin-glass panels in favor of a wraparound metal case and single, front glass panel. This change made the phone easier to open and repair than its predecessors. The iPhone 5S shares this same basic design. Unfortunately, it also has the same tamper-resistant screws along the bottom edge. You'll need a special pentalobe screwdriver to remove them.
