Well, it's announced anyway, and EA would like to release it this month...more details from the press release inside, and two more pictures...

Rock Band iPhone/iPod touch will include all four parts of your home console version: Vocals, Drums, Bass, and Guitar and will include 20 tracks that you probably already own for the home console. It also will include all of the console's difficulty levels, and you can play 4-player co-op wirelessly over Bluetooth.

There will also be a music store where tracks can be downloaded. Leave it to EA/Rock Band to make me spend all of my money on music I already have...

That's about it, no word on pricing yet, but I would guess $10. I'll let you know when it's up and how much you'll spend.
