I second the idea to call the ICE number. My daughter lost her Blackberry at some airport when it fell out of her bag going through the X-ray. A very nice ladt from Pittsburgh found it, called me (I was one of the ICE numbers), and I gave her my Fedex number to send it back to my daughter. Happy ending all around.
Maybe we were just lucky, but I'd trust the kind-hearted Pittsburgh finder before I'd trust the anonymous airline Lost and Found.
