Ah, the beautiful, ever-useful jailbreak and the developers that make it worthwhile. It's already unlocked the magic of FaceTime over 3G, and now it's making FaceTime capable with any old iPhone 3GS handset (thanks to the iPhoneIslam Team, who did the heavy lifting). Of course, lacking a front facing camera, the resulting video chat might be a little short on faces, but the functionality certainly isn't hurting anybody. Right, Apple? Hit up the app on Cydia and start streaming to your heart's content, and if you're wary there's a demo video after the break.
