So I found an iphone4 today on the sidewalk and the its passcode protected so I can't access any contacts to try to locate the owner to return it to him/her. When I connected it to iTunes it says to enter passcode before it can connect to iTunes. The phone says NO SERVICE so I'm assuming the owner turned had the service turned off. Is there anyway to contact the owner or should I just throw it away? Maybe return to AT&T?
