Über die Lynx Cheats
Level skip:

In APB, if you hold down OPT 1 and OPT 2, and run into a donut (or 
through the Donut shop) your quota will be filled and you will be returned 
to the station and proceed to the next level.

Skip to level 99:

When your quota is met, hold down OPT 1 and OPT 2 when you touch the
Officer Bob parking space. This will warp you to level 99. (The game will
not end, just repeat level 99 with random quotas).

Double Fuel:  

On Highway 12 you will find gas pumps right next to each other.  Park
directly in the middle of the two pumps and the gas pumps twice as fast.
