In iPhone 4, Apple has added another exciting feature for their device, and that is Face Time Video calling. For those of you who are wondering what it is, I’d like to tell them that its a video calling feature provided by default in iOS 4 and enables you to do a video chat with anyone using a iPhone 4 or iChat, over a Wi Fi Network.

This feature is without a doubt, among one of the greatest and long awaited feature that was announced in iOS4.  The iPhone 4 makes  use of its front VGA camera to capture your pic, so the image quality is not that good, but still its quite better than a typical VGA webcam.

The video calling feature in iPhone 4 is restricted to Wi Fi networks only, which means that no video chatting over a 3G network for now. Apple has made this decision due to some reasons which are unknown so far.

The face time video calling is developed on an open-source platform, which means that iPhone application developers would be able to use its feature in their applications.

Face time calling does not require any external setup of any sort, its embedded in the iOS 4. When you are on a good quality Wi Fi and know that the person you are talking to also has an iPhone 4 capable of video chatting, then you can start your face time with a single tap.
