During CES 2012, Research in Motion (RIM) announced the PlayBook OS 2.0 would arrive "next month", with that next month being February. At the end of this month, Mobile World Congress starts up and we should see quite the flurry of announcements and unveilings, one of which should be RIM's PlayBook OS 2.0.
RIM's Senior Brand Manager, Jeff Gadway, has assured PC Magazine that they're sticking to their promised timetable, and PlayBook OS 2.0 will ship "very soon". Very soon, and MWC seem to line up quite well, and RIM should have a decent presence at the show.
PlayBook OS 2.0 will arrive as a 400MB update, and brings a bunch of important features to the OS, including an Android App player, a native e-mail client, calendar, and contact apps. We should hear and see more about PlayBook OS 2.0 in the coming weeks, or when MWC hits.
