Hi, my name is Paul and I’m a Rooster addict
If you point your Blackberry’s browser to mobile.blackberry.com, there are several free downloads for your enjoyment. Among them are several addictive games.
I’ve been seriously hooked on Rooster, which is a superb remake of Frogger. My high score is currently just over 1000, on the second space level.
This page from RIM talks about the game and its development.
Free. Go get them all, play what you like. Highly recommended.
