Important safety tip, don't place your HTC HD2 on the roof of you car and drive off.
However, if you do, all might not be lost. The Talk Show host in the above video was loaned an HTC HD2 to review. He was distracted while leaving work and left the Windows Phone on top of his car. Once home, he realized what had happened, traced back his steps and found the HD2 lying face down in the road.
The HD2 didn't look pretty but the overall condition of the phone might surprise you.
