BlackBerry Bridge has again been updated, this time to version 18.104.22.168. The only major note is a fix for devices running OS 7.1. This probably isn't a sign of a BlackBerry PlayBook OS update as it has been many times in the past, but who doesn't love an update? If you're running the current version you should receive a notification to update, or you can head to BlackBerry App World to grab it now.
