Hacker named Intell at iFans forum has successfully ported iPod touch 4G’s Facetime app to iPad. The app seems to be working fine and provides a one way video chat with iPhone 4, iPod touch 4G and Macs and a two way audio chat between Apple devices with Facetime. The app as seen in the video above seems to be working fine on the bigger screen of iPad.
Here is the risky guide that you can follow to port Facetime to your iPad at your own risk

The iPad takes a few extra seconds before it will start to stream the video, just give it a while on slower connections. And because the iPad 1 doesn’t have a camera, the other end of the call will only see a black screen, but they will be able to hear you.
