While messaging on BBM is instant, unfortunately the activation is not. To manage a surge of new users, those who have successfully downloaded the app would not be able to use it right away. After registration with your email, BlackBerry will put you in a queue and you will be notified later once your account is ready. So far we have registered ours and we haven’t receive any notification after an hour.
While waiting for the activation, check out the official BBM demo video after the break.
