found locked BB with at&t logo on bottom, person at at&t store said they can't trace owner, looked thru this site to try to find out how to unlock it and found one person that said to start emergency call and hang up and then get password reset, couldn't get this to work. i posted description of device and where i found it ( Rt. 111 exeter nh ) on lostandfound.com, but so far no response, any suggestions? thanks curt
