UPDATE: Shawn (TwistMyMind) has come up with a step-by-step instruction to successfully load BlackBerry Messenger v184.108.40.206 (see below)
Warning #1: Please remember that this IS NOT an official release of BBM. If you wish to install this version keep in mind that this may cause your phone to not function correctly. BlackBerryOS and any other BlackBerryOS Official sites are not responsible.
Here is the steps I used to make it successfully load:
2. Install BlackBerry ID app (http://www.bbh-plus.net/downloads.php?do=file&id=2044)
3. Install BBM 220.127.116.11 (http://bb-h.me/bbm60056)
