No GSM. Suspect dead Calypso. What to do?

Yes, I should clarify that... Calypso seems to be present, but will not register the GSM network no matter what. Calypso is dead for certain values of dead.

I should add that when I tried to use GSM manually it would hang when trying to connect to the modem. (Logdump does show quite a bit of ATChat, so I admit I may not have been connecting to the modem properly, but I did try following a couple of different guides on the subject.)

If you can make more sense of ATChat logs than I can (my knowledge of AT is small, and is limited to having dialed ISPs on POTS modems many years ago; I have no knowledge of GSM) please have a look at my trac ticket where I have attached a few different logs.

Another possibility is that something is wrong with the antenna, but again, I don't know how to read AT well enough to tell if registration fails because of a problem with the modem (which I suspect, because it really did just die suddenly out of the blue -- it was sitting on a table doing nothing between the last time I used it and the first time I couldn't use it anymore) or because of lack of signal.
