Missed what happened. My friend with an iPhone 4 just called me to try out FaceTime. Very weird feeling at first, then became completely natural. FaceTime is on open standards, so hopefully it becomes more supported on other handsets and over 3G. Really cool.
He doesn't have cable so I FaceTimed him a half inning with the rear camera
Funny you should mention that, my cousin and i were just trying it at the apple store, not 2 hours ago. It only works with wifi for now, i believe.
