Me too ;-)

This is from QtMoko's modem plugin [1]:

	chat("AT_OPSYS=0,2");       // disable UMTS, use only GSM

I also added many other workarounds in QtMoko for the GSM. I think it's 
working quite good now, but not perfectly. Here is list of problems and 

* restart QtMoko after modem crashed. AT_OPSYS=0,2 does not completely solve 
the crashing and after the crash the serial line stops working, so i restart 
whole QtMoko [2].

* sometimes after resume the serial line is silent - i am closing the serial 
port before suspend and open it after resume and doing CLCC and SMS poll after 

* very rarely the modem after resume simply disappeared - the serial port file 
/dev/ttyHSO_Application was not existing at all.

* cant detect other side hangup in outgoing call - i do CLCC polling.

I am running the phone mostly with AT logging on. But sometimes you dont have 
time to analyze what happend.

Currently the modem with above workarounds works quite good, but i think many 
people expect it to be 100% perfect...
