Last time, someone just held a pocket magnifying glass against the lens. This time, blogger Colin Devroe attached the lens from a dead digital camera to the back of his iPhone McGyver-style and produced some nice results.
But what about low-light situations? Colin has got that covered, too. He mounted a small, giveaway light he picked up at last year's SXSW's keynote to the iPhone and found that it functions as a nice flash.
Good job, Colin! You've demonstrated the answer to the question, "Why are you holding on to those old things?" (Answer: "Because I might need it some day").
