There's something so cool about putting your sleek, 21st century iPhone into a rough-hewn, rugged looking case (but with soft edges, so your cell doesn't get hurt, of course). This handmade iPhone Slip Case ($12) is made of soft brown distressed leather, and only costs $12.
It's totally the kind of thing that James Dean or John Wayne would have carried. You know, if they had iPhones. And were alive.
