I got my iPhone 4 on launch day, and my daughter got hers yesterday. Today we had a chance to try FaceTime. I am in NYC and she is in Florida so it is something we will use often I am sure. I must say that it worked fine right away - clear picture and audio ... very easy indeed. Used both cameras and flipped back and forth with ease. There is a short lag between the time I touched the screen to change from one camera to the other, but once I realized and expected it, I stopped doing the "screen merry-go-round. LOL! Who else had had any experience with FaceTime? Where were the participants in relation to each other? What was your reaction to it?
