It looks like Nokia has released PR1.3 for the N9 without much fanfare. After the Finnish companylaid off some 10,000 employees last month, it was rumored that any future MeeGo updates would also be scrapped, especially considering that the N9 is the only Nokia smartphone to run the OS.
It seems that despite all of the internal issues Nokia has, there are at least a few people left in the MeeGo department, at least for now. Rumor was that this update was in preparation for PR1.4, but all of that was before the layoffs.
The update version number is v40.2012.21-3.001.19 and comes in at 204.8 MB. Quite a lot of users have already reported having received the update, so it's global rollout should be complete soon.
