The iPhone Lens Dial

Over the years there have been a lot of photography related accessories for the iPhone. Everything from stands, tripod-like gadgets, and even lens mounts. Some are a bit too ridiculous and some are pretty cool.

Here's another one I just came across at Photojojo. The iPhone Lens Dial. It's a gimmick, but it could be fun to play with. Here's how they describe it:

The iPhone Lens Dial boasts three optical-quality coated glass lenses: Wide Angle, Fisheye, and Telephoto. All wrapped up in a slim aircraft-grade aluminum jacket equipped with two tripod mounts (for portrait or landscape shots).

I'd like to see this as a built in feature of the iPhone. Imagine a small rotating dial on the iPhone that allowed you to choose between 3 lenses with different focal lengths. It'd be great to have a wide angle, a normal, and a telephoto lens built in.
