So you love Rock Band, but the Xbox 360, PS3, Wii, PS2, PSP, and DS just don’t offer enough ways to play.  Fear not, rhythm gamers; Rock Band is coming to the iPhone, and “very soon.”

The portable rhythm game, brought to you by Harmonix, will support 4-player co-op, allowing players to tap screens in rhythm as a team, as well as World Tour and Solo Tour campaign modes.  20 songs will fill the soundtrack at the beginning, but DLC tracks are planned.  Here’s the starting track list;

• "Attack" - 30 Seconds To Mars
• "Girls Not Grey" - AFI
• "Move Along" - All American Rejects
• "Sabotage" - Beastie Boys
• "All The Small Things" - Blink-182
• "Hanging on the Telephone" - Blondie
• "Learn To Fly" - Foo Fighters
• "Everlong" - Foo Fighters
• "Bad to The Bone" - George Thorogood & the Destroyers
• "Hymn 43" - Jethro Tull
• "Bad Reputation" - Joan Jett
• "Simple Man" - Lynard Skynard
• "Ace of Spades '08" - Motorhead
• "Debaser" - Pixies
• "Ladybug" - Presidents of The United States of America
• "Give It All" - Rise Against
• "Lazy Eye" - Silversun Pick Ups
• "Cherub Rock" - Smashing Pumpkins
• "Take The Money and Run" - Steve Miller Band
• "We Got The Beat" - The Go Go's

According to Pocketgamer, the game will support local multiplayer over Bluetooth and will use Facebook to support its online co-op modes. 

iPhone users all around the office are saying essentially the same thing; “I’m buying it.”  While the iPhone’s touch screen may seem like the ideal interface for a Rock Band title, I’m not so sure this game won’t turn out to be extremely boring.  Then again, with Tap Tap Revenge topping the charts, I suppose anything is possible. We’ll find out when the game releases “very soon.”
