Hmmm they managed to remove the home button to replace the battery. Uhhh the battery is not undernwither the home button. Glad the apple techs removed sh*t just cause what h*ll why not. Rather then removing what's needed to be the most efficient. Ohh and so they don't increase the variables of something else going wrong where the untrained idiots start poking around.
Gotta love even OEM repairs, somehow they still manage to f*ck it up. And even worse the touch I'd of the home button is tied to hardware on the mobo. So if u replace it the mobo goes as well. Increasing the costs quite a bit, what a disappointment on apples part.
Best of luck.
