Lumia 520 may be the next in line to receive Lumia Cyan update, if the Lumia Cyan tracker page is any indication. The Europe page shows that Lumia 520 on Orange in France has the Lumia Cyan available now. Surprisingly, it is the only market and only carrier for which Lumia 520 has Lumia Cyan update available. May be Lumia 520 in more markets will get the Lumia Cyan soon. Microsoft has been really slow with the update after Lumia 625 and Lumia 925 got it in first phase.
For catching everything about Lumia Cyan and Windows Phone 8.1 which includes:- Full Changelog, Hands-on demo videos, Tips, Tutorial no better place than our dedicated Lumia Cyan and Windows Phone 8.1 page.
