Hey there. I'm a long time iPhone user, but new to the 4. It's not like I don't know anything about it from the get-go, but there's this one feature I'm having trouble with. FaceTime seems like a great way to chat over wifi, but is it possible to do so over 3G? I can't seem to find a way to do that at all! And if it is available on 3G somehow, is it possible start a generic video call to people without an iPhone/FaceTime, like say, people who are using a Nokia, or something? I tried getting my friend to do start the video call because FT won't start without wifi. He kept getting the message: "Video calling not supported by the other handset," which meant my iPhone, of course. Please help!
