So i'm about to get an iPhone, once my current contract expires, and i currently have an enV Touch and an iTouch. With my iTouch, it has the silver back part of it and i used to have a gel case on it. Now although it would protect it when it fell, when i would take the case off, the silver part in the back looked AWFUL. It made it very dirty because somehow, dirt and such got in and couldnt get out. Also, the same thing happened with my enV touch phone. So i was wondering what cases have you came across that have the same result and what cases do not. Because im not going to pay all this money for an iPhone, get a case, and then once i take it off the back is all dirty.
