RIM has gone ahead and updated the version of BlackBerry Messenger available in the Beta Zone this week. This update brings us to v220.127.116.11 though it comes with a big caveat. They are asking users of BBM Music to NOT upgrade to this version. My guess is that is because of incompatibilities which is not promising. This is what RIM had to say about the update:
BBM Development teams have focused on fixing file and picture transfer issues. Additionally, this latest BBM beta release includes subscription payment support for platform-enabled applications.
