If you’re into iPhone accessories, or international spy missions, you might like this telescope for your iPhone camera.  The telescope gives you 6x zoom for improving the quality of iPhone photos .  The telescopic lens mounts to a built-in bracket on a hard plastic iPhone case (included).  Focus can be improved by manually adjusting the bezel on the telescope.

One important note- this gadget only works with the original iPhone, not the iPhone 3G. The lens is 7 cm long, and comes with a carry strap.  I found the iPhone telescopic lens at ThinkGeek.
