It's in a NIB file inside iTunes app.
Sorry, I'm not sure what the NIB file is. The front page gives a screenshot of the preferences, but it's completely different than my preferences (I'm running 7.7). My preferences look the same as before (Summary, Info, Ringtones, Music, Photos, Podcasts, Video). Also, there is a radio button the top left of the screenshot that I do not have. What am I missing? I'm looking at the iPhone preferences (iPhone is highlighted in iTunes).
Thanks!
