Best way to clean a severely dirty 3GS?
I have an old 3GS that I've been letting my mother use, and it's dirty. And I mean DIRTY. It has some hard to get off scum on it. I was just curious the best way to clean it? Including the front. My mother just upgraded to the 4s and we wanted to sell it. No one would buy it looking like this. A lot of it is the kind of dirt that you get from leaving a case on it for years. Thanks! - Justin
