I bought mine from the Apple Store online. It's the black one.
I did try washing the crystal film, and drying it lightly with a hair dryer, but I still end up with water spots under the film. And yep, there's definitely some sort of adhesive on the film...and if you rub it enough, it will come off. : (
EDIT: Anne from Power Support got back to me and helped me clean the film and reapply to the face. It looks pretty good now, although there is still the ridge where the film and the face don't meet (as in flashbackz picture). I was not able to reapply the wheel because of the weird smudge, which wouldn't clean off. Anne says that there's no adhesive too, so I guess I'm wrong. But I'm OK without the wheel cover.
I'll upload a clear picture of the Nano with the Crystal Film later so everyone can see the gap between the two. I have a pretty good macro mode on my camera.
