BlackBerry has pushed out a nice update to BBM for BlackBerry 10 in the Beta Zone today. The new update brings performance improvements to Glympse along with UI Polish and improved notification performance. They have also added improved avatar handling and more emoticons. Keep in mind this is still a limited beta release so only those who are in the program can get it. Still its worth checking to see if you are eligible!
Here is to hoping this gets general availability soon!
