This is a step by step video of how to tear down the iPhone 4. If you have any problems with your phone I would suggest taking it to a licensed professional but if you would like to give DIY iPhone repair a try please check out this video first.

Apple has really made the devices easy to take apart if you have the right tools. If you want to take apart your iPhone, you will need a separator tool, a small phillips and a small flathead screwdriver. Also, make sure you keep track of all of the screws you remove.
