Heh, stuck my iPhone 5 in a case literally the moment it came out of the box this morning. No screen protector yet because they're still on the way from Spigen. Spent a little time in my pocket alone, no keys. Looked at it tonight under a really bright overhead light, and voila, 1 cm hairline scratch in the oleophobic coating. Doesn't catch a fingernail at all, and completely invisible under anything other than direct bright light, but damn that was quick!
