What is the app from Cydia that allows unlimited 3G?

Also is there an app that lets you view YouTube videos in HD quality while on 3G?

There seems to be some app that allows FaceTime over the 3G with no charge. Is this true? Things like Yahoo messenger.

My3G works well. And you can't get unlimited 3G via Cydia. Only from your carrier.

3G Unrestrictor also works. Like previous poster said, doesn't give you unlimited 3G, just tricks certain apps to think its running on wifi.
