Oh, Internet, is there anything you can’t do? iChatr, a new app for the iPhone, is essentially Chatroulette for the iPhone. It’s pretty barren right now – I saw the same people once or twice – but the quality is pretty good and if you have a Sing-a-ma-jig, you can actually make dour iPhone 4 users smile. To move to the next person you simply swipe their face.
