Now that the Windows Phone 8 OS has gone official, the focus has shifted to the Windows Phone 7.8 upgrade for the older devices.
For now, we only know that the Windows Phone 7.8 upgrade will bring a few new features from the Windows Phone 8 to the older devices which includes the new start screen.
But now an alleged slide has leaked which was used in a Windows Phone 7.8 presentation reveals the features that are arriving with the new upgrade. The leaked slides include features like the new Start Screen which will arrive with three Live Tile sizes which users can customize.
There will be twenty themes which users will be able to use to customize their Windows Phone smartphones. With the upgrade, MP3 files can be edited and can be used as a ringtone, while the Internet Explorer has security updates and fixes.
While we do not know as to when the Windows Phone 7.8 upgrade will roll out for users it has previously been heard that the upgrade will roll-out, once the marketing for the first batch of Windows Phone 8 smartphone ends along with other Windows Phone 8 features like Rooms and Xbox Music.
