According to a number of sources, the Windows Phone 8 update -- codename "Portico" OS build 8858 -- is rolling out across a number of European markets for those using unbranded hardware. WPArea.de reports that they have received the notification to upgrade their unlocked Windows Phone in Germany, while a handful of our readers from both Denmark and Sweden have got in touch.

We previously looked at Microsoft unleashing the update late last month to Italy, Germany and Russia. The reports coming in this evening show a controlled release with more consumers now receiving update notifications. Have you received Portico on your Windows Phone 8 device yet? Let us know in the comments.

Thanks to everyone who tipped us!
