As some of you guys know by now, Microsoft has officially confirmed that the Windows Phone 7.8 update will only be making its way onto WP7.5 handsets come early 2013, somewhat of a bummer for WP7.5 owners especially since their devices will not be eligible for the update to WP8. Either way while a specific date of release has yet to be confirmed, a video was spotted recently where WP7.8 was seen running on the Nokia Lumia 900. The video is called a “quick preview” and it most certainly is that, basically giving us a quick rundown on how WP7.8 might look like running on WP7.5 devices. According to the uploader of the video, the version of WP7.8 running on the Lumia 900 is only the preview version of the software and it might not even be the final release. It’s not much to go on but we guess this is what WP7.5 users will have to contend with until more details are revealed, so if you’ve got a minute to spare, check out the video above.
