For an added cost of about US$149 (to process your existing unit or add it to the cost of a new one which you also buy from them) you can have your iPhone done in any of 29 colors from the colorizing company Colorware.

They use a special painting process and final layer that prevents scratches, and they do it for most new gadgets from PS3s to Wiis to Xbox 360s, or ostensibly, anything you can imagine.

Color your world here. Make mine Ferrari Red.
