We recently got an official upgrade from RIM to BlackBerry Messenger 188.8.131.52. The team at Driphter has rummaged up a new leaked version 184.108.40.206 with an OTA download link for all. There is no change log but they noticed some speed improvements in loading group chats and in general use. 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!
Thanks Tashanna for sending this one in!
