Some of the icons are pixelated. I don't see them letting something like that come to pass even on an internal device. Also, I thought they use iPod touches? I could be wrong though. I'm leaning towards this being fake.
Besides, there's no real reason to get excited over their iPods. They're just fancy POS's at the end of the day. 🙂 (by POS, I do mean "point of sale")
