Some of my apps just randomly shut down when i play them... I JUST re-jailbroke my iPod yesterday and thigns are already getting messed up. like i was playing SimCity and as soon as i build most of my city, it just shuts down and goes to the home screen. This has happened on almost all my apps EG: pocket god, touchgrind, cartoon wars gunner, TTR3. any advice you could give me?
