iBoy: Gameboy iPhone Skin
This is a skin that turns your iPhone into a Gameboy. But before you get too excited it goes on the back of the phone, not the front. Which means you can still use the phone as Apple intended. A skin that converts your iPhone into a working Gameboy – now we’re talking. You can pickup the iBoy skin for $10, though we’re not sure if there is a version yet available for the iPhone 4.
