The release of the iPhone 4 and FaceTime will revolutionize the way that we communicate. Sure there are (and have been) other services out there that allow us to video chat, however with the release of FaceTime for iPhone 4, I think video chat will be revolutionized for one reason and one reason alone. It is no longer necessary to create an account with a 3rd party service like Skype. You just need your phone number (and obviously the $199 iPhone 4).
So no that you have the iPhone 4 and FaceTime working, how do you tell which of your contacts also have FaceTime? That was the first question I asked myself when I started playing around with my new iPhone 4, “How can I tell which friends have FaceTime?” The simple answer is, you can’t. Just try calling each of your contacts with FaceTime to find out if they have it.
To make a FaceTime call, just open up a contact, scroll to the bottom and click the new FaceTime button. Best of luck!
