iChatr is a free iPhone application that connects you to other random iPhone 4 users in the world. To make the app work, you have to be connected to WiFi and wear headphones. If you get bored of a person, then just swipe the screen and you will be connected to another person. This is a nifty app for those who are into the speed dating concept. I have only 2 friends that have an iPhone 4 so this gives another opportunity to utilize the FaceTime feature more too. The application idea is very similar to webcam/chatroom website Chatroulette.
