I saw a ad on the main macrumors (might have been 9to5) for iphone cases. The cases looked pretty sweet. However, the ad has gone away and now that i actually have my iphone i cant find it. So, whats a stylin' case for the iphone 4s? I kind of don't want to put a case on it because its a pretty cool device, but I should to protect (hopefully) against drops and scratches.
