iPhone 4 Battery Replacement
Beware, watch the video, there is a antenna cover/clip that pops out easily when you remove the inside screw and has to be replaced. This was quickly mentioned in the video but NOT mentioned in the guide. Also I stripped every screw I removed/replaced, the #00 screw driver doesn't work to well and I had the original philips screws, not the pentalope screws. Also, the read all the other comments, I wish I had known the battery cable wasn't pre-bent...its tricky doing yourself.
Be careful is my word of advice and have tweezers around too!
