FaceTime is a great concept because it is free, but its being restricted to Wi-Fi (for now) also makes it limited. Fring is an application that allows 3G and Wi-Fi video calling between iPhone 4 owners. Best of all, though, is that Fring is cross-platform and enables callers using Android, Symbian, or iPhone 4 to chat together.

The video demonstrates a brief video chat between an Evo 4G and an iPhone 4. Fring can also multitask on iOS 4.
