I'm more likely to attempt making my own iPod than try knitting these iPod mittens, but if you're so inclined, Sean of Sean's Soapbox has provided the pattern. While the iPod is poking out of the mitten for this picture, the pocket is big enough to fully enclose the iPod, though I don't know if you'd get a snug enough fit to walk around and feel secure. Very cute idea, though, although they may be better for the lighter weight models like the Shuffle or Nano.
