Windows Phone 7.8 has been revealed ahead of schedule for Nokia Lumia devices.
Over the weekend, reports in Holland (via AAWP) claim that a number of Nokia Lumia 800 handsets have been receiving a sizeable four-part software update. This lifts the OS from Windows Phone 7.5 to Windows Phone 7.8.
The last we heard of it at the end of November, Microsoft had claimed that the update was headed for an early 2013 launch.
Elsewhere, the Windows Phone 7.8 update has been made available for a wider array of Nokia Lumia devices through Navifirm, as revealed by My Nokia Blog.
Windows Phone 7.8 will update the all-but-obsolete Windows Phone 7.5 OS with a number of key features from the new Windows Phone 8 OS.
While the two operating systems remain completely separate, the Windows Phone 7.8 update will add the Windows Phone 8 Start screen to older devices, along with its more flexible live tiles. It'll also boast double the number of theme colours of Windows Phone 7.5.
Windows Phone 7.8 will also boast new lock screen features, such as the ability to set up a lock screen password system to prevent accidental swipes.
