Video chat done the Apple way
FaceTime, the excellent video calling application originally introduced for the iPhone 4, is Apple's answer to Skype. It allows you to keep in touch with friends and family on Apple devices via video chats. Open Facetime and you'll immediately see yourself on screen and you must sign in with your Apple account to get started. Once done, FaceTime will sync with your address book, allowing you to immediately call anyone with an iOS device.
