If pacman by Benny Chow locks up/crashes your phone, try playing in silent mode.
After the music starts, press S on your keypad. This mutes the sound.
I love having Pacman in my pocket and being able to play it anywhere, but having to do a battery pull or turning off quickly to catch it with " uncaught exception " was a pain.
Also, I find the game to be faster with the sound off.
It seems as though this game is right at my curves processing limit.
