Take this post with a large grain of salt, but we have a possible video of a very early beta of Windows Phone 8.1 running on a Nokia Lumia 920. The video shows new interactive live tiles and the new notification center. The video itself is of very poor quality.

All current Windows 8 Phones will be able to upgrade to WP 8.1. Windows Phone 8.1 is expected to be released in Q1 2014 after GDR3 in holiday 2013.

Do you think this video is real or fake? Let us know in the comments below.
