I have found several cellphones and with no idea of stealing the data, I would simply have returned the phones to their owners no questions asked. That is, if their phones weren't locked and with no identification on them. The first thing I do when I find a phone is to call the last dialed numbers to see if I can find out who owns them. If they are locked, then I will remove the battery cover to see if there is a name.
If you lock your phone, put your name and number on the battery cover!
By the way, I have gotten back two Blackberries this way. Both left at restaurants.
You can also put it in contact info so when you turn on the phone your info is right there and they cant unlock it...
