If you want to fix your broken iPhone 4 or change the broken back on it you will need a new tool in order to open the iPhone 4 up. Apple has recently decided to replace the #00 phillips screws on the bottom of the iPhone 4 with some new ones called "Pentalobe" screws. They are a rounded 5 point center of the screw and very tiny which means they will be easy to strip. DirectFix.com has on order some tools that will allow you to open the new screws up but because of the delicate nature of the screw we highly recommend that when you do remove them you replace them with the good old stand by phillips #00 screws like the original iPhone 4 came with. We have included some photo's showing the difference of the Older iPhone 4 with the phillips screws and the newer one which we just purchased 1 week ago that has the Pentalobe screws.
