Hello, I'm going to be getting my first iPhone 4 very soon, and would like help picking a case. I've read reviews on this forum and other sites, and the consensus seems to be if you want ultimate protection then you need to get the Otterbox Defender case. However, I really don't want a bulky case. I would like to carry my iPhone in my pocket. Can I get anywhere close to the durability of the Otterbox, with more portability? Thanks.
