Hey, just found this out the other day, but GameGuardian works on Civilization Revolution 2 for your phone. Mainly for the gold though, but having unlimited gold makes it easier no matter the difficulty. Basically just search your gold as DWord, and adjust the value to whatever you want. It's easier if you wait till it gets in the 100's mainly an odd number, makes the search easier so you're not looking for 1,000's of value's. But, it doesn't seam to let you do the achievements after you've done the value change.
