This step is a important notice that i am not responsible for any damage done to your device or any mishaps that may happen along the way. You are preforming this procedure at your own risk. Sure if you do happen to mess up then you can contact me with any questions. But make sure if you are going to proceed beyond this step that you have 5-6 hours of free time ahead of you and a full stomach. (It took me 7 and a half hours to complete mine but that was after looking for plenty of screws on the ground.) This operation does void the warranty but given the fact that At&t does not provide insurance i didn't really care.
This operation is not for the fain of heart, steady fingers are necessary!
Remember apple made this as difficult as possible to prevent people doing this, to proceed you have to take out almost every single component in the phone.
(is that all the warning i need to include?)
