The update includes Airplay, which enables wireless streaming of video, photos, and music from your iOS device to Apple TV. AirPlay is an exciting new development for iOS device owners who also have Apple TVs. As long as the devices are on the same wireless network, they automatically detect each other. AirPlay also lets user multitask while streaming video to Apple TV. Unfortunately though AirPlay is a one-way street. Users cannot stream something they rented on Apple TV to their iOS device. The iOS 4.2 update also included the introduction of AirPrint feature, which is the wireless printing solution for the iPad. Other minor changes Apple squeezed into this update were, a better Word document fidelity in iWork, multi-tasking and Game Center."
