I love this mod and looked at the silver button and thought it should look better in black so i made a black one. Here she is with a maychy matchy pearly white tip.
It is made from black resin called jet black and the installation was not bad. The battery cage is held on by 4 screws, then the board is held on by 2 screws. The board only needs to be lifted up a little for the button to be accessed and not to mess up the touch screen.
