I was having this exact problem. Fortunately, the latest version of iOrder will SSH into your iPod and put it in the right place.
Where that place IS after the update, I don't know. I have scoured the system, opening every folder, unzipping the root.zip file, and I can't find anything about N45AP.plist.
I'm thinking they hid the folders or something. How to see them again, hmm...
