[maemo-developers] how to manage phone Profiles in Maemo

[From: ibrahim]

cheers;

I was wondering if there are APIs to programatically manage/change the 
phone profile (normal-silent-offline-meeting ..etc) in Maemo 5.
Can I put the phone to silent or make it offline for sometime ??? Is 
this controllable?
What component of Maemo 
<http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/Architecture/Top_Level_Architecture> 
is responsible for Profile Managment?

thanks in advance;
