At first I thought this was just a show-off thing, but when I got a BB, I realized it's actually quite a PITA to shut off. Mine had a "sent from my blackberry on the Telus network" default signature, which I hated. To shut it off, you have to set up an online profile, open the phone to get the serial #, then manually go in and shut it off. And you can't do it from the BB, has to be done from a desktop. Not a big deal for someone who understands tech stuff like me, but I can see it being too much for someone who isn't used to it, so they might just leave it.
