Windows Phone 7.8

Windows Phone 7.8 is an upcoming (and perhaps final) OS upgrade to the Windows Phone 7.x platform.  Windows Phone 7.x is based off of the CE kernel while Windows Phone 8 allowed Microsoft to transition over to the much more robust NT kernel. Because of this, current Windows Phone 7.x users (Nokia Lumia 710, 800 900, HTC Titan II, Radar, etc.) cannot upgrade to Windows Phone 8.

Announced back in June 2012 at the Windows Phone Summit, the 7.8 upgrade was said to come after the release of Windows Phone 8 later that fall. Indeed, Microsoft has now confirmed that it is due to hit carriers and devices sometime in “early 2013”.

Features have not been officially confirmed in the update except for the inclusion of the new Start screen experience i.e. three Tile sizes: small, normal and the doublewide. In addition, re-branding of Zune to Xbox Music and the new Xbox Games icons have been changed, plus the Bing lockscreen wallpaper feature. Other smaller changes are expected in the final release build, pegged at 7.10.8858.

Currently it is unknown which phones will get the update nor which carriers will support it, but Nokia and HTC are expected to fully embrace the rollout.
