Only a few days have passed since the last leaked version of BlackBerry Messenger, and now a newer version (.54) has been found online. This version of BlackBerry Messenger will only work on devices running OS 4.7 or higher. I wouldn’t recommend installing this leaked app, unless you have experience doing so in the past. It’s also recommended that you do a full backup of your device via BlackBerry Desktop Manager before installing.
After doing a backup you can download BBM 188.8.131.52 over the air (OTA) by pointing your BlackBerry browser to: http://bit.ly/BBM541
