If you have a WiFi in the house....SECURE THAT SUCKER! Gotta have a key.
As for finding a BB...you gotta turn that sucker into the carrier because you would want someone else to do the same. I worked retail and found my share of neat phones and the first thing I always do is look for Mom, Dad, Sis....something like that in the address book so I can call them and have them inform the owner where to find their phone.

Just my 2 cents.
