FaceTime on iPod touch lets you hang out, catch up, and goof off with friends in an entirely new way. With just a tap, you can see what your friends are up to — literally. Witness a prank in action. Or watch your friend on the other side of the country crack up at your stories from last night — new iPod touch to new iPod touch or iPhone 4 over Wi-Fi. And all you need to get started is an Apple ID and an email account. You can choose an email account you already have or, if you prefer, set up a new one. You’ll never see fun the same way again.
