if iphone games are written in java, how hard would it be to port the game to blackberry assuming you had access to the source code? wouldnt you just have to find the same api's for blackberry and just match them up? i dont think it would be that hard.
iPhone apps are writing in objC. It's a totally different programming language. Porting a game over from the iPhone would be really tough. You would probably be better off just starting the game from scratch and just copying over a few methods here and there.
