Figured one portion out via the "help" function on BB messenger (duh)..
The fix to prevent BB messenger conversation from appearing in the main message list is:
1) From messenger screen hit MENU |
2) Click Options
3) Change the 'Show Conversations in Message List Field' to NO
4) Press the menu key
5) Click Save
when you want it back showing in the main messages just do it again and type YES.
