I think it was wrong choice for you to have n950 as main phone. My suggestion to get another cheap phone for calls/msging. And use N950 as devkit, anyway it has pixel syndrome disease
http://forum.nitdroid.com/ - Nitdroid forum (but no n950 real support, as dev didn't get one)
Or you can use search on the forum here, as those topics were discussed hundred time, you can as well check wiki on this site or meego.com. Good luck.

To all other people:
I was rude on forum few times, but even when i rude or sarcastic, i'm trying to provide answer, but not just be rude. BE CALM.
