Argh. Technology. T-Mobile's website said the upgrade would make my Blackberry work better. The upgrade said it would reinstall all applications and restore all data. What wasn't clear was that it wouldn't reconnect the device to the enterprise server it was previously connected to.
Or in other words, not something you should do if the Blackberry isn't owned by you but is instead maintained by your company. Because you're going to have to take it in and admit you were screwing around with it and broke it and beg for forgiveness.
Blech. Yep, that's me. Just smart/dumb enough to be dangerous to myself.
