FaceTime is a one-tap feature on the new iPhone that will work from iPhone 4 to iPhone 4 using the regular calling functionality. Simply tap on the FaceTime button located where the Hold button is now to initiate a video call.
iPhone 4 makes video calling a reality. With the tap of a button, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories. iPhone 4 to iPhone 4 over Wi-Fi. No other phone makes staying in touch this much fun.
