Hello, I found a iphone 4s in a trash can near my work. the phone was ringing loudly with a message on it saying " this iphone has been lost. please call me. 363-6" also has a call button on it. but when I press call I get a recording telling me the number is invalid. There is also a passcode lock on the phone so I can't even check the contacts to call anyone who might be able to get a hold of the owner by other means. I was wondering if there was any other way of tracking down the owner, maybe through AT&T or apple? Its a long shot but I know these phones are not cheep and would like to see it returned to its owner.
