Hey there. It seems like all the cases I've seen so far mainly protect from cosmetic damage. I need a case that makes my iPhone virtually drop proof. Anyone found a compromise between size and shockproof? I don't want to have a brick of rubber in my pocket, but don't believe the slim-line cases will do much in the event of a drop. (I've had one already, 2 weeks in to a new 3GS, on concrete, I'm a clutz) The IvySkin Quattro looks promising. I'm new to iPhone, and so far am very impressed, but tired of worrying about the killer drop. Thanks.
