I received the latest SAS news today.
The Mobile 'ban' has now been lifted slightly, it goes into effect when the crew announces it and ends at gate parking/seatbelts off.
The idea is to allow passengers to talk if delayed. The captain can also lift restrictions after the announcement, if the A/C is waiting for an extended time on a taxyway.
So, still no phoning when taxying towards the gate.
