Well, as far as i understand, that's still not correct. Imagine i want
to restart the phone app while using GPRS? I think it's a valid use
case.

Moreover, even provided zhone is the only app using the GSM
resource, are you sure that gsm0710muxd will power-cycle the modem?
What i see in the frameworkd log is that %CSTAT "response" is never
received if i don't restart the muxer daemon. If you need a proof,
i'll attach the logs to the ticket i've created.

Do it once, then if 'SIM busy' received, wait for the %CSTAT. What's
wrong with this approach?
