I'm digging the metallic blue hue on this iPhone case (it also comes in a number of other colors), but this particular case provides more than just protection to your mobile: it also holds your credit cards and cash! The Case-Mate iPhone Credit Card Case ($30) is great for when you're headed out for a night on the town and just want to take the necessities: phone, ID, and a few bucks for a cab. Not sure how I'd feel about toting around my credit cards out in the open like that all the time, but I guess when you have limited space in a tiny clutch, it could be a lifesaver.
