Hey. I have noticed that my iPod touch's Music Store is in French, however, everything else is in English. I don't have an account set up with the touch at the moment...
well, I kinda was in the opposite situation. Everything was in French except my music store which was in English (and I wanted French, cause that's where I'm from even though I left the country). I sorted things out by switching the store location: go to the bottom of the store's main page, you should have some sort of tab that says "My Store". Just switch to UK, and you're set.
