This post helped me a lot. Summerboard in Installer.app moves the dock to the top of the screen. Use Summerboard in iBrickr.it says i must install summerboard through installer, but they only have 2.11 they wont allow 1.1.1 . when i did just install the 2.11 it moved my dock to the top of the screen. then i uninstalled it crap is still on the top of the screen. i think i may have to restore and start over unless you have a fix?
