Gratuitous lost cel phone story:
I was in Chicago. My flight landed late and I was racing to a friend's place. There were huge piles of snow everywhere. The taxi got me where I wanted to go. I pay, the taxi leaves, and I'm half-way into the building when I realize my phone isn't in my pocket. Crap! I race back to the street and sprint up a 5-foot snow drift. My phone must have slipped out my pocket. The cab was gone.
I called my cel company and they helpfully deactivated the phone and I was probably going to be forced to get another. Then I got an email from the cabbie. When you turned on my phone, the custom message just said my email address. The cabbie emailed me and said he had my phone! He even mailed it back to me without charging me. I'm still amazed. Everybody should have their phone displaying their email address!
