If you're looking to replace the keyboard/keypad-good luck. I finally figured out how to replace the keypad after about 30 long minutes of contemplation. It was a complete nightmare. It takes a lot of patience and determination and finesse to remove the existing OEM keypad. You have to push and prod and wiggle it out. I will tell you that the keypad is removed best from the front side of the phone. I used a thin, sharp knife blade to start the peeling away process which helped a little.
