We know the iPhone can do a lot of things, but turning it into a microscope never occurred to me… Brando is now selling an attachement for the iPhone 4 that will do just that. It is a special slide on 60x lens with an LED illuminator. It actually has 3 LEDs. Two for the microscope and one for displaying watermarks on notes. This looks like a lot of fun to play with. And at $17.50, it would make a great stocking stuff for your favorite iPhone 4 geek.
