Right, 2G = 2 gigahertz. My phone does mode switching automatically
under MS. I am able to use the modem on that platform. For $40.00 a
month I get free Canada wide calls, texts and a few other features as
well as so called unlimited band-with. In this case they mean they
don't throttle the connection til you hit 5 gig of transfers.

I used the term GSM  to refer to any modem that supports one or more
of the protocols in the GSM evolutionary family, including the 2.5G
technologies GPRS and EDGE, as well as the 3G technologies WCDMA,
UMTS, HSDPA and HSUPA. (Most of that sentence comes from a reference
website ;-)

I thought I'd try to access the modem on my phone using Debian, just for fun.

I confess to finding udev a little frustrating, but I don't
necessarily find it a problem. My SYSFS problems and resolving parent
child relationships are, in my mind translational problems. You'd
think I'd be able to just get the OS to ignore the reported file
system. Once the device is booted, the modem is always on right? I
just have to figure out how to prod the mode to switch from storage to
stream or block to character or whatever.

Nautilus is ok as a file manager, it just tries to mount everything
that gets connected to it and I can't figure out the proper sequence
to send to correct that problem.

I use linux because I always feel like I learn something, not just how
to do something.
