If you have ever experienced the pain and despair of picking your once shiny iPhone off the ground to find a disgusting fissure across the screen? Don't panic, if you are reading this, you have probably already been turned away by your local Apple store. With the replacement part, a steady hand, and little bit of luck, your phone can be as good as new! I would rate this process as moderately easy, assuming you have some basic tinkering experience or technical knowledge. I accept no responsibility for the damage you may or may not inflict on your iPhone while performing this tutorial. I highly recommend that anyone attempting this process, carefully read through my entire tutorial before proceeding at their own risk.
NOTE: This tutorial is done with an iPhone 3gs but the process is EXACTLY the same for the 3g, a specific replacement digitizer is required for the 3g however.
