Rock Band iPhone Launches at $10

The iPhone version of Harmonix's Rock Band launched today on the Apple App Store, carrying the relatively hefty price of $10.

For that price, you'll get 20 songs and four "instruments" to play on each, though all modes--including singing--are simulated by tapping the notes with your finger.

Up to four players can jam together over bluetooth. Downloadable songs will also be available by way of a built-in store.
