If you're riding the beta train of BlackBerry PlayBook OS', you'll be happy to know that OS 220.127.116.110 is now available. This is a beta release and meant for developers only, and as such will most likely have a good amount of bugs. If you haven't installed a PlayBook beta OS before, we suggest you steer clear and just wait for an official release. If you're a developer or just want to give the beta a go, you can do so from the link below. Just register your PlayBook PIN, sit tight for a bit and the update should be available to you. Be sure to drop a comment letting us know how it is!
