Hot on the heels of the leaked Windows Phone 7.8 features from a few days back, a short clip of the update has emerged online, running on Nokia Lumia 900. See it below.
The short clip surely doesn't reveal much, save for the resizable tiles, a la Windows Phone 8. In any case, Windows Phone 7.8 is scheduled to arrive in early 2013, so the wait for the Apollo treatment of your first-generation Lumia shouldn’t be too long.
Thanks to Redsteel for the tip!
