600-nokia n9_09A major firmware update for the Nokia N9 has begun to roll out. The version of this update is 20.2011.40-4 and it includes such things as music controls on the lock screen, improved multitasking, and NFS tag reading. It sounds very much like the PR1.1 update for Nokia N950. I'm just installing it myself over the air (OTA). It seems to take quite a while. The PR1.1 update in my N950 took about 20 to 30 minutes to install, if my memory serves well, and in this update it say that it might take up to 40 minutes. So be patient and do not panic if nothing seems to happen. Since the update 218.6 MB, a WLAN connection is recommended. Making a backup prior to any updates is always a good idea.
