Hours ago I announced the official release of OS 188.8.131.521 for the 9850/60, and already other carriers have trumped it. We now have OS version 184.108.40.2066 for the 9860, from multiple european carriers. If your carrier is not listed below, do not forget to delete the Vender.xml and read out install guide. Be sure to report back to us with any Bugs and Fixes.
This is by far the quickest OS update I have ever seen. 220.127.116.111 lasted a total of 11 hours before it has been replaced by 18.104.22.1686. Enjoy the new version guys!
