Looking to buy a phone for the wife. she wants a droid 4 for the slide out keyboard and 4g shes seen the screen and likes it. the thing is trying to get one off ebay without the update. to be certain you can not get to the phone battery. the phone i was looking at on ebay says perfect condition just got the phone and it has no back piece but the blue case he bought works. i was confused if this was possible. and how easy it would be to fixed.
