BE VERY, VERY CAREFUL, HERE!!

-The repair went horribly wrong during this step, for me. I pulled-up on the suction cup, gradually increasing force. Instead of just opening a gap to get the plastic prying tool into, the whole thing gave way at once. This damaged the connection between the display assembly and the rest of the iPhone.

-During this step, I would recommend placing a rubber band around the phone, over the home button and one near the top of the iPhone for good measure. Even better, invest in the "iSclack". In my case, it would have saved me about fifty bucks and three days without a functional iPhone.

-When I reassembled, The screen was blank, but I could still sync with iTunes. I may have been able to replace only the cables, but I wasn't sure how extensive the damage was and I was done messing around with it. I replaced the whole display assembly, and now it works just fine.

-This was STILL cheaper than buying a new phone, and I learned a lot. Overall, it was a good experience.
