I have various games on my iPhone which I have downloaded on my iPad as well now, but lots of them I have finished before. Now I need to start them all over again. Things like scores and achievements can be saved in Game Center. But in the game itself that isn't the case. Is there anyway to do that? To unlock all the stuff again? The same thing also happens if you delete a game and reinstall it on the same device. I learnt it the hard way
