Does anyone know of a black adhesive skin for the back of the iPhone 3g / 3gs? I'm looking for something like a best skin ever or zagg invisble shield, but black NOT transparent. Ideally, it would cover both the entire back of the phone, including the top, bottom, and sides, up to the metal bezel. The reason I want this is because work bought me a new 3GS (lucky, I know), but it's white, and I really don't like the way the white iPhones look. I could get a silicon skin or something, but I prefer the thinness of a BSE or invisible shield-type skin. Thanks in advance.
