Microsoft revealed Windows Phone 7.8 last week. The system update got a bit of stage time details were still a bit lite. The Windows Phone team posted the video above and it should clear up some confusion around the new Start Screen.

Windows 8 brings a host of new features, but most are hidden from the user, involving the platform’s kernel. For better or worse, the biggest visible change involves the Start Screen that will feature re-sizable tiles. But current Windows Phone will not be able to jump on the Windows Phone 8 bandwagon due to hardware requirements. And so, to likely prevent an angry mob of users, Microsoft is bringing the new Start Screen to current phones through the Windows Phone 7.8 update.
