Annie Leibovitz seems to love the camera in the iPhone 4S as is, but if you'd ever hoped the snapshot darling were a bit more flexible, then Photojojo's new Lens Dial may be the solution. Available as a case that's compatible with the iPhone 4 and 4S, users are able to rotate between three different lenses -- including fisheye, telephoto and wide-angle -- to achieve their desired effect. Naturally, the enclosure will add quite a bit of thickness and heft to your handset (it weighs ten ounces, or twice that of the iPhone), but it also piles on flexibility, too, such as tripod mounts for landscape or portrait scenes. Shipping now for $250, the iPhone Lens Dial seems like the logical step after you've taken Holga's option for a spin.
