Windows Phone 9 is said to bring a number of goodies, including side by side multi-tasking and actionably notifications.
Now NokiaPowerUser’s sources have told them that the Developer Preview of the OS update could hit devices as early as January 2015.
The OS update, which is said to unify Windows RT and Windows Phone, will, according to their sources, also be available for all devices, including the humble Nokia Lumia 520, but some features may be reserved for higher end handsets, such as side by side multi-tasking which will require phablets 4.9 inches and more.
