I was actually looking it last night, I bought the game from Magmic's website, in their support/FAQ section it had a limit of 3 devices a year. Whether that includes the original device, I really can't see myself going threw 3 blackberries a year (at least I hope not lol.)
So I went ahead an spoiled myself and got this game.
If only my bank roll wouldn't reset to $0 every time I close the game lol. (Is that normal?)
