Rock Band from EA is coming to the iPhone and iPod touch and Mashable has the details:

Just as is the case with the original, Rock Band for iPhone offers four different instruments that you can play: vocals, drums, bass, guitar. Each option offers a game experience that is unique to each instrument, so you’re playing the actual drum part when you select “drums,” and so on.

Should you sync up with friends and play over Bluetooth, be prepared to be blown away. The real-time gaming experience is incredible, as yours truly can attest to, and even goes so far as to highlight other players’ activities on your device as they happen.

Head on over to the link above for me info and screenshots. They think it's "awesome". What do you think?
