So you sometimes get the SIM dialog and sometimes not?

On my older GTA04A3 this bug is probably hidden, because the modem never 
powers off...

It might be interesting to enable Settings->Logging-> modem AT commands and 
check/send /var/log/messages when it happens.

Hmm this is known bug with modem - it disappears and reappears few seconds 
after. For me this happens very rarely and i restart qtmoko in this case. 
Maybe this time it didnt work well. We still need better solution preferably 
in kernel for this bug.

It would be nice to try to debug further where is error. Did you see POWER led 
green blinking when you expected the incoming call? QtMoko does this when 
reads incoming call AT command.

So if you see POWER led blinking and the phone does not ring, then modem is ok 
and there must be some problem in software. If it did not blink then the 
incoming AT command didnt come over the serial line.
