I installed the extendedpreferences.app, restarted my ipod, and now all i get is a blank screen with my dock at the bottom without any icons. I SSH'd in and there was a folder called Preferences.bak and Preferences.app. I deleted the .app one (it was the "extended" one) and used the ".bak" one (backup?, but I still have the same problem! PLEASE help!! I REALLY do not want to restore- again!!
