We're getting reports from several users, including our own staff members, of BlackBerry Messenger being down. This happening just less than a week ago from the BIS outage we all experienced. You have to wonder what the deal is. And I for one, don't believe in coincidences. Are you experience any issues with BBM?
*UPDATE*
It seems we are slowly getting service back to both Email and Messenger so sit tight, you should start to get very belated messages. Hit the forums and let us know where you are starting to get your service back so we can keep track.
