Check out this video of a BlackBerry Pearl causing a flashlight to freak out. This BlackBerry user posted a video of his Pearl's strange behavior on YouTube. If it's doing that to the light, what could it be doing to your brain?
"My Pearl is about 2 years old.. and a refurb. It's always done weird things when too close to speakers - makes them sputter out all kinds of noise due to its radio antenna signals. Last night I discovered a new.. "trick" this thing has. I put it next to a rechargeable LED lantern/light and suddenly it started blinking WILDLY. When I moved the BB away, it stopped. The light is controlled by a physical button, and to my knowledge does not have any radio controls."
