When your phone rings just place it face down on a table or desk or something similar. Ringer automatically mutes and phone goes into silent mode until picked up again.
jptbay - where did you find this nokia care suite? Sounds like it might fix my problem. It's April 21/ 2013 and I still cannot update this phone and get the same error code 80180089.
I tried to reply yesterday, but could not login for some reason.
In this very thread, on page 10, post # 95, is a link and a good description of what to do.
Here is a direct link to that post: http://communityforums.rogers.com/t5/forums/forumtopicpage/board-id/WindowsPhone/message-id/1064#M10...
Hope that helps, John.
