babyj,
With the various issues you are having I am going to suggest you re-flash your Voqs ROM with the latest software. You can find the correct ROM from VOQ
HERE. You have already hard reset and you are still having strange problems. Generally with the headset issue you would just push the on/off button down until you get the QuickList and scroll down to More and select Automatic. That should get the Headset off.
To check which ROm you have go to Settings>About and scroll down and note the Operator Number. That is the ROm that you want to see if there is an update at the VOQ site.
Let us know what you do. I have a VOQ and can walk you though it.
