I shared Power 99FM Philly's photo.FYI: I figured it out! Your cellphone doesn't have a name: These are "short codes" for EVERYBODY'S facebook names. It's our Facebook IDs. BUT: Since it works (a name pops up) and it's not hyperlinked to a profile (because presumably all of the REALLY OLD facebook numbers – like 3 digit ones – are ALL long gone)… this trick works!
Use http://findmyfacebookid.com/ – look up your ID number and try it.. You pop up Good troll though!^
