But then we have the problem that we cannot enter a PIN code if there is 
one.
We will be waiting for '#QSS: 3' (SIM ready), but this will only follow 
after '#QSS: 2' (SIM unlocked).

My Samsung Galaxy Note seems to deactivate the SIM in flight mode - at 
least the SIM contacts disappear, I have not tried the other things yet
With the HTC One X you have to enter the PIN when you exit the flight mode.
