I'm looking for a case for my iPhone 4 (at&t). I want something slim (I don't like the Otterbox cases that are so bulky and cover the beauty of the iPhone design), but I want it to protect my phone if I drop it, without the case breaking into pieces. Anybody know of a good case to go with? I've looked through Amazon.com's entire inventory of iPhone cases 3 times over and can't decide on one. Help!
