Apple have rolled out an update for the new Apple TV that enables AirPlay so you can stream video from an iOS device to the Apple TV. I think this is really going add to the value of the Apple TV which without any hacks or apps has had little use in my house so far.
AirPlay lets you stream digital media wirelessly from your iPhone, iPad and iPod touch to your Apple TV and AirPlay-enabled speakers. So you can watch films and photos on your widescreen TV and play music through the best speakers in the house.
I should be able to give it a try and report back when I get back home later this week
