The OpenBSC project appears to be making good progress on this, so I
don't think it's wholly unrealistic. After all, the vast majority of
phone vendors consider free drivers for graphics as "unrealistic";
this community is in the business of changing these expectations.
There are several clear advantages to having open code for the
- Bugs in the modem can be actually fixed (or at least are more
likely to be able to be fixed). It's my understanding that the
problems I had with GSM reliability on the GTA02 was due to the
modem being buggy, though admittedly I don't know if this is
something that could have been fixed at the firmware level.
- Awesome things like p2p mesh phone networks can be experimented
with; it allows a greater level of the "doing things the designers
never anticipated" sort of hacking.
- Security that you aren't being spied on more than is required by
GSM. Your assurances and explanations of the GPS part of the modem
being disabled are good and make sense, but more generally it's
nice to be able to see exactly what's going on, and check for
