The 6 screws to open the case ARE NOT PHILLIPS! They are Tri-Wing, a Y shaped driver, not + shaped. If you use a phillips head screwdriver, you will strip them quickly, and then you actually will have to drill them out. Use the right tool every time!

I have a much deeper appreciation for the workers who assemble these phones. Makes working on a laptop seem like working on a diesel truck in comparison! I highly recommend a clean, well lit workspace and at least an hour just in case something's fidgety. Problem areas include transferring the camera/speaker assembly and removing the contact pad from the home-button assembly. Remain calm and do not use too much force. Be prepared to spend some time on those things, otherwise a fairly simple process. Much nicer than the 4/4S, and I hope Apple continues to factor in the ease of screen replacement for all future models.
