I replaced one of these monday and it was not that bad. I ordered a new flex and used a heat gun to soften the glue on the flex so it could easily be removed and reinstalled. Be careful with the vibrator part of the flex it can be damaged easily. Take your time and install just like it came off and you will have no problem. This is a pretty easy phone to work on. I did not need to purchase any extra parts to complete the repair. I used double sided tape to replace any tape that did not restick. If you use heat to remove the covers the tape should come off with no problem.
