Sure ... debug the issue, fix it, submit a patch. You'll probably need
deep knowledge of GPRS RLC/MAC layers to do that properly.

I'm not even sure they do.
The code is more of a "demo" than a complete system, a lot is missing
to properly decode everything (for, it just "guesses" the GPRS channel
from a single assignement and then listen on all timeslot of that,
which mostly a short cut to grab stuff, proving it's possible but not
that much more, unless the cell has only 1 GPRS arfcn).
Also since it only support GPRS and not EDGE you can pretty easily
miss stuff ...
