UPDATE: Kudos to BigBadWulf, one of the mods @CrackBerry for stripping out this version of BBM and dropbox-ing it!
Fubaz let us know that BlackBerry Messenger 188.8.131.52 was included in the latest OS 184.108.40.2066 leak for the BlackBerry Bold 9650. This version is a tiny incremental update from the previously leaked 220.127.116.11 but if you have to be on the bleeding edge check it out at the link below. Similar to previous versions this will probably only work on OS 6.0 devices.
I am not sure who stripped out this version of BBM and posted it on DropBox but thanks! Let us know if you figure out who it is so we can credit them. Like the regular BlackBerry Messenger updates this one clocks in at about 3MB so it may take a bit to download.
Warning: Do not download and install these updates if you don’t know what you’re doing. Incorrect procedure or just bad luck could render your BlackBerry inoperative or unstable. In other words proceed at your own risk!
