So I got my iPhones screen replaced in august it's a 3gs, and before the replacement my home button seemed flush with the screen, but ever since that day they replaced it, when touching the home button and rubbing your finger to the sides you can tell it's very recesses and is kind of sharp. The top of the screen near the sensors are recessed and you can feel that it's sharp rubbing your finger over the chrome lining, but down by the dock connected the screen is higher than the chrome bezel which explains the home button. Is there anyway I can fix this by myself, maybe following the guides on ifixit like I was going to replace it but just try to even it out?
