Did you select the checkbox when you were presented with a list of applications to install? I'd be surprised if Brickbreaker was missing...if you had it before on your monochrome BlackBerry.

If worse comes to worse, you can use javaloader.exe to remove the brickbreaker game from the 3.7 OS, and install it on your 4.0 BlackBerry;

Try checking your BlackBerry Desktop Manager
-> Application Loader
-> Next
-> Look at the checkboxes and enable BrickBreaker
