I dont have an iphone myself, but it certainly wasnt hard for my friend to extract the app from his jailbroken one. if that is considered cracking the game and not just the Phone/OS, then I certainly understand. I will delete the levels regardless, and I apologize. I had no idea the huge amount of pirated .ipa files floating around out there currently.
on another note, are there any plans to sell more levels for that N900 bounce game? from what Ive seen so far, Ill buy anything Rovio puts out for this thing. very impressive.
