iPhone doesn't work in direct sunlight
OK, I have a weird problem for you guys. My iPhone 3G will not work in direct sunlight or when any strong light source is hitting the light/proximity sensors. Whenever you shine a bright flashlight onto the top of the phone, it freezes until the light is removed. If I'm outside, I need to cover the top of the phone to use it.
At first, I thought this was a simple software problem, but it has persisted through restore after restore.
Here's a vid.

Now this is where it gets weird. The phone only freezes when I use an incandescent lightbulb as the source (or sunlight). If I use an LED flashlight or a fluorescent lightbulb, nothing happens and it works fine.
