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?
