The forthcoming Flash for the iPhone caught my attention recently, as did HP’s iPrint photo App, and now USBfever is expounding upon the iPhone’s camera further.

iPhoneFreak reports a new collection of “kits” meant to enhance the camera without all the bulkiness of other camera add-ons.

The lenses are magnetic, some weighing as little as four grams, and offer wide-angle, fish-eye, and telephoto picture taking capabilities. The hardware is surprisingly cheap, all cost less than twenty bucks.
