As the title says... Whenever I tap any app to open, nothing happens. The icon is selected (goes dim) and I can move them around, but nothing opens. No App Store, Cydia or stock app will open. No error messages, loading screens, etc. Trying to open them from Spotlight/SBSettings doesn't work either. I've jailbroken my iPod at 3.1.2 with blackra1n. Tried re springing and rebooting too Has anyone else had/have this problem, and maybe have a solution (rather than a restore)?
