Well, the wiki says a firmware update for the modem is possible, but I'm not sure how. They are coordinating with TI to get the update out as soon as possible.

Meanwhile, here is a wiki page describing the SIM cards that work and that dont:

Also, here is the bug reported for the AT&T 3G simcards:

Maybe the bad luck associated with this bug has something to do with its bug ID (666) :P

Anyway, hope this helps.

I have Rogers. My friend's card was also Rogers, but he bought it
telling them "I have an unlocked phone" and they sold him it for 35$.
Anyway, in Canada, except for "Ice Wireless" in the north, Rogers owns
all of GSM (because the CRTC are stupid), so it's definitely not that
the phone can't talk to Rogers.

The firmware update, is that for the modem or just the OS
(kernel/rootfs)? Can the modem's firmware even be updated?
