Here is a classic, old school game - "Copter" The goal is to safely navigate the helicopter through a cave. Simple, easy to use, but good enough to get yourself hooked, and want to start over! Start new game, then use any key on your Blackberry to apply power.
I love this game. I've had it on my phone ever since I came across it. My highest distance, that I can remember (I've reinstalled OSes on my phone a lot so I've had to restart) is 5027.
