For the fun of it, updated my N9 (Denmark) and have no issues, also, so far nothing to report improvementswise.
FB/Twitter/Qneptunea etc all works.
Openmode kernel, and Inceptiom + Powerpack also installed.
I didnt have any 3G issues before this either

Also, I did reboot - since acording to some, that should/might bring up the issue.
Not, after reboot (thanks thedead) my date/time was still correct - autoupdate is set from carrier.
