So here's what happened...I installed the new os6 on my 9700 through desktop manager(6.0 Bundle 2534) but when I ran BBM from the bridge on my playbook, it brought up a message about BBM not being installed or the version not being supported and now the icon is simply gone!
EDIT: The bbm icon re-appeared but the same message turned up. This time, I got to write it down: BlackBerry Bridge plug-in for BlackBerry Messenger does not exist, or your version of BlackBerry Messenger does not support BlackBerry Bridge.
