I tried to move an app on my jailbroken iPod touch 4th generation to the system partition to free up space. I moved the app from /var/mobile/Applications to / and then created a symlink in /var/mobile/Applications which points to the actual .app in the / folder. After i did this i went and opened the app i moved and it worked fine. However, i tried to open the settings app and it crashed immediately. I rebooted to see if that would fix it, but now all of my system apps are missing from the springboard and openssh is not working. Can someone please tell me why it did this and how to fix it.
