Thanks everyone for the help, it's appreciated. The IT folks here took my BB in to an "authorized repair center" for fixing when Nextel (my provider) was unable to tell them what to do. I made an offhand comment about simply restoring from backup when I get it back and they freaked -- told me I can't do that and it has to remain connected to the BES only and .... and ... so, I think I will restore from backup anyway!
What's the worst that can happen: they will have to re-activate the BES on my unit. Big whoop.
