I just asked and it was indeed a Tungsten C (the Tungsten C was a pretty l33t beast for a handheld in that era, I had one too and loved it a lot), but I got the story wrong - the wifi wasn't secured at all. Let me remind you again that they'd replaced their wired network with this unsecured wifi network. Their business was online marketing for companies even more clueless about technology than they were. (Replacing the unsecured wifi with wired was indeed the first job.)
