At CTIA Wireless in San Diego EA Mobile secretly announced that Rock Band will be making its way to the iPhone and iPod Touch this holiday season.  The details of the game are very limited at this point and it was only shown off in a short video demonstration which focused on a single screenshot of the game’s menu interface.  What we can tell you at this point is that the game lists four instruments : lead guitar, bass, drums and vocals, and there will be four player capabilities via Bluetooth.  No details on an exact release date or pricing were revealed.
