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! :P

   Use http://findmyfacebookid.com/ - look up your ID number and
   try it.. You pop up :P Good troll though!^
