Ok, how about FaceTime on the new iPhone 4? Has anybody tried it?
This article says that once you are connected, and the second party has accepted the call into FaceTime (rather than refusing and merely getting a voice call) that you don't use up any minutes on your Cellular data plan.
If that's so, I need an iPhone 4 buddy to practice with. I haven't got anybody to call ... who also has an iPhone 4 and can practice FaceTime.
Gulp. I can't believe I'm volunteering for this.
