Realm: Geekitude - Subrealm: I'm confused

As a geek, I'm bemused by many aspects of modern life. For example, on the WEEI Red Sox Network (which Grace listens to religiously) Verizon has been advertizing cell phones with "Bluetooth Capability" .
Does this mean that your new cell phone is going to win all Denmark for itself and Norway, and make the Danes Christian? Or is it a small furry being from Tau Ceti? I'm so confused...
