Windows Phone 8.1 GDR1 features demoed on video

Windows Phone 8.1 GDR1 (Cortana China)

A video showing off Windows Phone 8.1 GDR1 running on a Nokia Lumia 1520 has popped up on YouTube.

Unfortunately pretty low resolution, it does show the new start screen folders and Cortana doing its thing in Chinese.

Developer Preview users are expected to receive GDR1 as an update next week, which brings a much longer list of features.  Read more about them here.
