Having for many years a George Costanza wallet wreaking all sorts of lumbar havok upon my coccyx and spine, I now favor svelteness of pocket: anything that isn’t my iPhone, a small wad of bills, a couple cards and my keys is simply too much.
I think I’m in love with this ingenious, minimalist iPhone 4 case by TRTL BOT: it seems like it was made just for me, fusing a standard attenuation-reducing iPhone 4 case with a slim pocket for up to three cards and a small fold of cash.
Speaking of small folds of cash, it only costs $30, and if you’re still on an iPhone 3G or 3GS, TRTL BOT sells a similar case for $5 less. Go get one: Jerry Seinfeld would approve.
