I think this is awesome. I would try to put in some help if I could, as long
as someone else told me what to do (:-). I have experience with fairly
low-level C programming and I did have a job writing laboratory control
software (in Forth) when I was in college (1980s). I have several
Osmocom-class phones I have purchased over the last year. I did run the
hello world app on a phone, just to make sure I could. I compiled the tool
chain myself with a script I found and customized that made a really clean
install (let me know if anyone is interested, but there are better scripts
out there now). Most of the cell stuff talked about on this list is above my
head, though I have gained a basic understanding of what's going on. I found
the c3 lectures fascinating, and watched quite a few. I'm definitely
interested in doing something for this project if I can.
Harald, I know you and the other people contributing to this project are
interested in this more from a research and understanding perspective.
But I also agree with RMS about the need for a fully open phone. You guys
have revealed just how weak the GSM network is, with its closed stack
assuming that all participants were noble knights who always followed the
rules (:-). It actually concerns me just what the telcos might be capable of
doing, especially after seeing the talks on silent SMS messaging.
There's no good reason for this software to be so closed. This is the big
one too. There are lots of other areas where proprietary software is
dominant, but few affect as many people directly as cellular phones. I also
have no doubt that a usable phone would get a LOT of attention. Could help
encourage efforts in other areas. Color laser printers are another area of
concern, because of the embedded ID on every printed page.
I am not surprised in the least that RMS is interested, even very
