Hi, I have used my iPod Touch 2G for about a month and had this strange behavior twice. Only the apps that came pre-installed can be started (mail, safari...) but none of the purchased or free apps can. They start to display the app but quit in about a second. Restarting didn't do anything but then I downloaded a free app from appstore to test it and suddenly all apps worked again! this happened one more after a few days which could be fixed by downloading another app. I was wondering if anyone noticed this kind of behavior on their 2G iPod Touch?
