iPhone 4S TPU Skin Case Accessory Cover Compatible with Apple iPhone 4 4G 4GS AT&T Verizon Sprint MiniSuit LCD Cleaner (Clear)
This is the most perfect \\"case/cover/protector\\" that I could have ever imagined for my new iPhone.  It isn't as obtrusive as the other full covers are and it's super easy and secure to hold onto the phone with the slightly rubbery-feeling bumper but not so much so that it hangs up sliding it into your pocket.  It also keeps the face of the phone above any surface you put it on and holds it there with the rubbery texture of the bumper.  It's literally all I could ever ask for in an iPhone protector.
