I did complete but took a little longer than I anticipated. The "do not remove" sticker was a pain because it tore off in little pieces, and my battery was hard to get unstuck(good adhesive I suppose). In the end I did get the battery changed, the only thing that doesn't work now is my camera, but I'm sure it was 100% user error. Oh well I just need the phone to work till the iPhone 5 comes out.
