If u want to bypass the wait for the bbm- try this!
Download BBM for either Android or iOS
Run the app, fill in your email address as per normal, click next
Once your email is registered, force close the app. On iOS, this can be done by tapping your home button twice and swiping the app away. On Android, you can go to Settings, Apps, BBM and stop the app from running.
After the app has been closed, go ahead and reopen it. From there, you should be able to create an account or login.
