I have a OtterBox Commuter and a Speck Candyshell for my iPhone 5. My main concern is which one has more of a risk of scratching the phone from dust getting inside, people with the candyshell or the commuter, please comment on the condition of the chamfered edges on your phone. Update: So today I was cleaning a replacement phone that I got about a week ago from the Genius Bar, and I noticed a small dent/chip on the side (not on the chamfer, on the actual side and not more then a mm in size, probably less) however, it is still anodized over, I looked at my case (speck candyshell) and I saw something that is around the same size and in around the same place, but I think it is just a defect in the rubber. My question is, could the case have caused this, or was it out of the box like this but I didn't notice? I've only had it for a week.
