All of you who have done the mod where it moves your applications folder to get more space, doing a restore wont undo it. If you do a restore, there wont even be a symlink for the applications folder, the entire ipod will think its where it was moved to. This isnt necessarily bad except when doing a gui sftp it takes alot more clicks to find the folder. To make the ipod go back to the way it was, delete a few of the root folders and applications folders in sftp, and do a restore by holding down the home and on/off button for 25 seconds.
