We've just got word from a Windows Phone Central reader that the Portico update is pre-installed in a Lumia 920 which was received from Dutch retailer KPN. According to the tip the build presently listed on the device (8.0.10211.204) matches what we've previously reported on when talking about the latest Windows Phone 8 update.
There has been speculation that Nokia is pushing out hardware with the latest build already installed, which is now confirmed with the recent reports. The company has had the update on its servers (though some were pulled) for some time but should you still be waiting on the update to hit your Lumia 920, there's a way to retrieve it manually.
Thanks, Daenney, for the heads up!
