I recently got the new iPod touch 4G 32gb in white and I've got about 12gb of games on it. A few of the ones I've tried so far, when I get into the game and play it for a while it just seems to force close and put me back to my homescreen. Is it a problem with the game because my iPod is brand new. Some of the games that do this are Shadowgun, Gun Bros, Contract Killer (normal and zombies) etc. Why is it doing this?
