I am beyond excited about this case that I just discovered on Chip Chick. I have long complained that although my iPhone has an excellent camera that takes great photos, it's useless in less-than-direct light. Now, finally, a solution.
The Beamer ($32) is a hard plastic case with a built-in light. The light is battery powered — so it won't drain your phone's batter — and stays on for 10 seconds at a time. It's perfect to use as a light for your phone's camera, or just as a flashlight.
I recently wrote about an app for the BlackBerry that turns the flash into a flashlight, and I have to admit, I was jealous that the iPhone would never have the same ability.
