It's good to hear there are still honest people in the world!
I have installed the app and made a wallpaper for my own, and I hope it never comes down to me losing it, but I'm prepared.
It would be nice if more items had such easy contact info. I was visiting a campus in September, and found some guy's Blackberry and it took me 4 hours to track him down. It was utterly useless that his friends were getting my emails alerting them I found it and to tell him to call it, but they just emailed to HIS address which of course dumped it back to the blackberry. It was a facepalm day.
