Introduction
I have no idea why you would ever need to replace these buttons, but then again I'm not omniscient so there may be some reason to do this outside of a full case replacement.
The exterior case buttons include the Power/Lock Button, Volume Buttons, and the Vibrate/Ring Switch for replacing buttons with cosmetic troubles.
This will be a lot of work, but if you are really set on doing this, here are instructions on how to accomplish that.
This guide is only for replacing the external button faces visible on the outside of the case.
