Find Tinman's post with his MA86.plist (or however its spelled) and upload it to your iPhone. He's got instructions on where to place it, sorry I can't copy/paste the URL in on my iPhone and i'm not about to try to write it out. But it's in the summerboard 1.1.1 thread.
Basically your icon listing file is borked
NO NEED TO RESTORE! JUST UPLOAD THE FILE TINMAN PROVIDED!
