Apple is changing the way FaceTime works to support a camera-equipped iPod touch and possibly the iPad as well, escaped details show. Rather than require a phone number as on the iPhone 4, it will use one or more e-mail accounts attached to an Apple ID, which in turn will be linked to the device. BGR understands that the approach would depend on a new push notification system in iOS 4.1 to handle requests on non-phone hardware.
