So, I did a backup and sync'd some new tunes and podcasts and all seemed well.... until later that evening. While sitting in a restaurant, I tried to launch some 3rd party apps while waiting for my food but none of them would launch. They would ALL quit immediately. All the default Apple apps work fine, but everything else quits. I've already restarted the phone twice, and am wondering, should I back it up again??? Thanks in advance for your help. Oh and by the way, I did search and haven't seen this problem anywhere else.
