How much trouble can you get in for hacking an iPad/iPod game?

I got this game for iPad called "Gun Bros"(wicked awesome free game) and getting war bucks(a currency in the game that's almost impossible 2 get) is very hard 2 get, and all the best guns and armor, u need war bucks for and I know I will never be able 2 get that many war bucks, and I know I could easily hack it, so I was wondering... How much trouble can you get in for hacking an iPod/iPad game
Oh I thought I should add that u can either earn war bucks or buy them SOOOOOOO...
