I've gotten a $100 finders fee for returning a 3gs to it's owner. I found it on the ground in the middle of the night when I was out with some friends. I called all the contacts with the owners surname, but noone answered so I took it home and tried again in the morning; his wife finally answered and ten minutes later the owner turned up in a huge Audi and gave me a nice finders fee. :)
