USBfever is selling 2x telephoto, 0.7x wide-angle macro, and fish-eye lenses for the iPhone. They attach with a magnetic ring with a self-adhesive backing. Now, it's no secret that the iPhone camera sucks, but they are so prevalent that some have managed to get better-than-mediocre pictures.. At US$16.99 each ($19.99 for the fish-eye), it might be with it to pick one up. Throw in Camera Bag (App Store), and you have a nifty little toy camera!
