This version was released in 2009. I've never played it, but it looks like it has all 16 characters, all the backgrounds, all the moves and everything. Due to the size of the screen, the backgrounds have been changed, with animation being kept to a minimum and much taller stages.
I don't have a BlackBerry, so I can't play this, but the reviews I've read often mention the cumbersome controls, as trying to do dragon punch motions on tiny keys is never easy. Many reviews also state that the BlackBerry version of Street Fighter Alpha is the better game, so perhaps BlackBerry owning Street Fighter fans should go for that instead.
