My girlfriends iPhone 4S dropped on the floor and both the screen and real glass panel cracked. So being the geeky engineer that I am, I rushed to the opportunity to be her hero by fixing the screen and rear glass panel all by my self. So I fixed it and became her HERO! Can you say.... MEGA POINTS!!!! Yeah Baby....
The process went very smooth. I was able to follow the instructions on-line and only had two minor little problems that I just didn't pay attention to. But two hours later I was able to replace both the screen and rear glass panel. I tested the phone and everything worked like nothing had gone wrong. Once again, my geeky engineering skills came to the rescue. :)
None. The process went smooth. Thanks IFIXIT! You guys helped make me look like I have handy-dandy man skills.
