I'm looking at the iSkin case for my iPod and now I'm trying to find a car mount that will work with it. I think I might want a cupholder mount since I don't want to modify or stick anything to the dash. Does anyone know of a cupholder mount that will work with the iSkin and hold it firmly in place? I suppose what I'm thinking about is that the difference in overall size of my iPod will change due to the thickness of the iSkin. I'm not completely stuck on purchasing the iSkin so other recommendations would be nice too! I have a 4G iPod.
