So I recently dropped my iphone 3gs on concrete, and it was unprotected and the screen cracked along with the back. Fortunatley, the guy at the Apple store was a very cool guy and replaced my iphone 3gs free of charge seeing as the store was jam packed and i waited paitently for 2 hours. But i feel as if i definatley got lucky and if this were to happen again i would be paying big bucks for a new one, which is why i really want a good case. Ive heard great things about otterbox and am contemplating on getting the defender or commuter. I would really hate a bulky case seeing as the iphone is slim and sheek, and i feel like the defender takes away from that however provides amazing protection. while the commuter doesn't offer as much protection, it still keeps the phones slim and sheek profile. anyone who uses either one of these cases please give me feedback as to which one i should go for. thanks.
