Microsoft has made the decision to change Windows Phone from a Windows CE base to a Windows 8 kernel base, which means that current handsets cannot receive the Windows Phone 8 OS. It’s not all bad news though as Microsoft announced at their developer summit last week that they will be updating current Windows Phone 7.5 handsets to v7.8.
The Windows Phone 7.8 update will not bring all of the new Windows Phone 8 features to existing handsets, but will bring some new features, including the new Windows Phone start screen.
Microsoft has posted a new page on their site which reminds users that current Windows Phones are still worth buying and will sport the new Start screen. Keep in mind that the company has yet to announce a majority of the new OS features, so there is likely to be much more in the 7.8 update than what is currently being announced. Below, you will see Microsoft’s Ben Rudolph demoing the new start screen on a Lumia 900.
