Microsoft has released a preview showing how the next version of Windows Phone 7, 7.8, will visually look. As you might recall, when the company showed off Windows Phone 8, it also announced that there would be no upgrade path for any Windows Phone 7 devices. However, they also let us know that those users would be able to upgrade to Windows Phone 7.8 in order to get the most obvious and visual feature--the new Windows Phone home screen. Once upgraded to 7.8, users will be able to resize all of their tiles as easily as Windows Phone 8 users can, and in the video above Microsoft's Ben Rudolph walks us through the experience.
