You're welcome. :)

Right now all my knowledge of GPRS consists of just this one paragraph
from Harald Welte's paper:

(Paragraph 6.1 on page 8 in the PDF.)

Given this highly limited amount of GPRS knowledge on my part, I'm
afraid that I won't be of much help with GPRS until *much* later down
the road, when I'm ready to try integrating (and learning) GPRS, well
after I get all basic GSM functionality (voice, SMS and CSD) fully
working in the gcc-built FC GSM fw.

Have fun!  Here are some tools to get you started:

Now this is truly interesting - are you saying that you are seeing
differences in SMS handling behaviour between moko11 and my leo2moko,
and that leo2moko works better for you in this regard?

Details, please!  I find it rather improbable that moko11 would have a
fatal defect in something as basic as handling incoming SMS, hence me
trying to understand exactly what it was that didn't work for you with
moko11 and got fixed with leo2moko.

Don't get me wrong, I would *love* to find out that my fw has some
actual functional improvement over moko11, beyond the "feel good" of
having a viewable source, but let's first confirm that it's real and
not imaginary...
