OT: Found lost iPhone, how to find owner?

[kramnnim]

So, the other day I rode past what looked like an iPhone on the side of the road...I was too lazy to stop and check, so I didn't. I rode past it again today, and sure enough- it's an iPhone. I brought it home, charged it...and it's locked.

Any ideas on how I can find the owner? (other than posting in the newspaper)

Connecting it to iTunes doesn't get anywhere. If I put it into DFU mode and restore it, the contact info will be lost...right? I can't use the emergency dial to get the caller ID, either...
