iOS not saving games
I'm playing PA2 on an iPhone 4 (4.3.3, 32GB). I've solved the first 2 puzzles several times. If I leave the game (either by pushing the Home button, or for some other reason, e.g. I receive a telephone call), when I re-enter the game I have to start from the beginning again. Nothing has been saved. I'm getting tired of re-solving the same two puzzles and wading through the dialog every time I want to play.
Also, as others have noted, the sound -- especially the dialog -- isn't good.
How can I leave the game and save my status?
