Help! I have my ipod touch jailbroken, and have downloaded loads of apps. I recently downloaded a gameboy emulator. the icon for it was nothing, just a black square with a ? inside it. when i clicked on it, the screen went back to the "SLIDE TO UNLOCK" page, and when i unlocked it, the springboard was blank! Anyway, now my springboard is blank, like there are no icons. The top is still there with the time, battery, and iPod written. i still have my background and dock, but there are no icons! What can i do to fix this??
