if you want this, petition @SituationsApp on twitter. They have the knowhow and they have an excellent app for Symbian. They will need to repartner with Nokia to get native access, but this can happen.
This is what I miss in Lumia 820 and I missed it from the day I switched to Xperia X1 from Imate SP5m. HTC who was the OEM had implemented this in the Imate. X1 I missed it but got G Profile from ageye. It worked on my Aspen too. But now have to manually switch to silent at night, switch on bluetooth while driving in the morning, set ring volume to mid at office, make it high when reaching home, etc. Too bad Nokia or MS did not think of this app.
