Alright, the basics are out of the way, let's tear this sucker apart! First step is to pull off the small plastic strip that rests under the keyboard. Take your plastic spudger or plastic opening tool of choice and work your way under either side of the plastic. Once it is loose enough grab it with your fingers and pull it up towards the top of the phone and set it aside.
Go figure that the cell companies would pick the very first and easiest piece to remove to stick their ugly corporate branding on. Oh well! If you'd like, feel free to take a bit of fine grit sand paper to the logo on this piece now that you've got it removed!
