Photo of the sky with sunlight peering through clouds, as seen in Shrewsbury, MO. This is actually almost exactly how the scene looked IRL, which is a high praise of the iPhone 4's camera and HDR abilities—it's not so pronounced as to take the natural beauty out of a photo, but enough to strengthen the contrast ratio a bit.
The iPhone 4 is a great video camera, professional audio recorder, photo camera, and mobile Internet access device. I'm glad to be an owner :)
