Last night when I was applying a them to my 2G touch something screwed up and I couldn't open any apps. I'd tap the icon and it wouldn't even open then crash. It just didn't open at all. The only thing that worked was SBSettings and all I could do with that was reboot/respring/safe mode and after all of those I still had the same problem. But after locking and then unlocking the iPod everything worked again...? Anyone else had that?
