Iphone kept shutting down, Apple wants $97.00 to replace battery
Scary at first, second....what the !&&* have I done! ....exhilaration when it powered back up.
read the instructions twice, watch the video,and dig in. If I can do it, anyone can! Ifixit saved me $80 and now I can hold out for the Iphone5 !
