I actually let everyone know about this a little while back, and it’s pretty cool. Pretty much the same as Yahoo!Messenger Video calling, or Qik, or even Skype(Well more like Skype with Group Calling), compatible iOS 4.x and Android 1.5+(Sorry Blackberry) devices (1GHz and above recommended) over WiFi, 3G, or 4G. See the video of it in Action! @TatWza
