RIM has gone and done it again. They have updated BlackBerry Messenger to version 184.108.40.206 and we have no idea what changes and fixes this version brings. Hopefully it is worth the reportedly almost 6MB download through the new App World webstore installer. (if you download it from the on device App World it is only reporting 3MB) Let us know if you spot any changes!
Kudos to @Guatiao for pointing out the update!
