iPhone Applications–Here’s some great news for you iPhone-owning Rock Band aficionados out there. The Rock Band iPhone app just hit the App Store and is now available for purchase. As expected, game play is very similar to the hit Tap Tap Revolution game. On the upside though, it does come with 20 rockin’ tracks by default already such as Sabotage (Beastie Boys), All The Small Things (Blink 182) and Aces of Spades ’08 (Motorhead) which guarantees you’ll be jamming for hours right from the get go. If the 20 standard songs aren’t enough to satisfy your Rock Band craving, you’ll be happy to know that it also features in-app purchases for additional songs. Up to 4 players can play simultaneously (via Bluetooth) so you can share the fun with all your bandmates. The Rock Band iPhone app is retailing for just $9.99.
