The main things are the bezel and battery door. I also changed that bottom rubberized piece to the plain black one (no myfaves logo). I wanted to install the G1 trackball because the ring around the ball is also black but when I got mine it had a weird white spot on the ball that didn't come off so I left it out. Also, the T-Mobile keyboard works better for the blacked-out look because it doesn't have the gray keys like the AT&T one.
