Hi, i am going to buy the new iPhone 4S and I need a case for it. The case should protect the iPhone but it shouldn't be like too thick. I heard that the Incipio NGP is a good case but is there a more "interesting" case? I don't want just a simple black one... Or what about a bumper+skin(like that one: http://www.zagg.com/sport-leather/iphone4.php#football)? would that be enough protection? Hope you can help me!
