Wandering the halls of the CTIA convention in San Diego, MobileCrunch spotted a small kiosk dedicated to Rock Band Mobile...
Sure enough, no iPhones in sight just a couple of Verizon handsets. Above the kiosk, however, was an LCD screen endlessly looping through a demo reel of EA Mobiles portfolio and therein lied the gold. Right at the end of the reel, it pops up clear as day: Rock Band for iPhone and iPod Touch.
The site has since confirmed with sources that the game exists, will have premium content, and supports 4-player multiplayer through Bluetooth.
