I've had this problem before. Jailbreak it with QuickPwn, and then install a bunch of apps from the iTunes store, a week later, the apps crashs everytime I open it. And it's only apps that I got from iTunes App Store, not any other ones. So I restored it, did everything again, about a week later, same thing happened....anyone know why? I have 8GB 1stG iPod Touch on 2.2.1 Thanks.
