Earlier my colleague Steve wrote about the US$249 Photojojo iPhone Lens Dial, an iPhone accessory that gives iPhone photographers access to an array of three camera lenses on rotating dial. For those of you who like the ability to add lenses to your iPhone, but don't like the $249 price, I recommend the Olloclip, a $69 slip on 3-in-1 lens for the iPhone 4 and iPhone 4S.
