Sure ... debug the issue, fix it, submit a patch.

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 ... Cheers, Sylvain
