FaceTime - FaceTime is the video calling technology introduced by Apple on the iPhone 4. Apple later extended support for FaceTime to other devices.
FaceTime takes advantage of a digital camera on these devices that faces the user to allow for video calls. It shows the caller to the receiver of the call, and vice versa. Calls can be made between any FaceTime compatible devices, i.e. from iPhone to Mac, from iPad to iPod touch.
FaceTime only works on Wi-Fi; it is not supported for 3G networks. This is a restriction imposed by cell phone companies, as the FaceTime software is able to work on 3G networks.
On an iOS device: iOS 4 or higher, a supported device
On a Mac: Mac OS X 10.6.6 or higher, a compatible camera, the Facetime app.
