So, I just got a brand spanking new 16gb iPhone 3gs, and loving it so far! However, I need to get a case for this bad boy, cause it always feels like it's about to slip out of my hands. I'm looking for a skin case that is made out of that soft-touch matte rubber (much like the soft-touch back that was sold for the Palm Pre, or the back of the HTC Touch). Basically, something thin and light that will protect against the occasional drop, but also something that won't stick to the inside of my jeans pocket. Any recommendations?
