BBM ( Blackberry Messengger) is actually is produced by Research In Motion (RIM)
and more user use Blackberry for acces BBM


Confirmed: BBM is now available if you are using US IP. If you are not, try accessing the URL after some time.
If you are already using the leaked APK, you will have to uninstall it before the new version can be installed.
How to skip the queue and register immediately
If you have already downloaded the app and you are waiting for the mail from BBM, here is a workaround for that. This will work with both Android and iPhone.
Use the email address ny3237@gmail.com when you are asked to enter your email. This will get you past that screen.
Sign up with your own email address.
 Do not use the IDny3237@gmail.com to sign up.
