ok i tried this and i think it will work but when i looked in my computer the only itunes related thing was for the camera THATS ALL!!This worked excellent for me,
Plug in your iPod
Go to "My Computer"
Open your iPod's drive (F for me)
Make sure you can see all hidden folders (If you aren't sure go to Tools, Folder Options, View Tab, and check Show)
Open the folder "iPod_Control"
Open the folder called "Device"
Rename the file "_locked" to "_unlocked"
Hope this helped
