While some sources suggest that there are no BrickBreaker cheats, a gamer posted a guide on how to skip levels in BrickBreaker, try your luck and follow these steps:
Note: This guide is for a Blackberry Pearl (for curve it's the Alt key, not the left caps key).
1. Start a new game and press OK to start playing level 1
2. Before you shoot the ball press shift (bottom left button) and then back (button to the right of the wheel)
3. This will take you out of the game to the opening screen, press menu (button to the left of the wheel) and select new game
You should then skip to the next level!
The strategy to beating BlackBerry’s BrickBreaker game is to "survive". Another gamer said you must play conservatively until you’ve gone through all 34 levels — twice to be guaranteed of a high score.
You can try this BrickBreaker Game Strategy, add a bit of patience and practice and you're good to go.
