I just checked the website of Nokia and i see Lumia 520 is available with Cyan Update. Now all i need to know that i am with Preview for Developers. Do i have to downgrade to from 8.1 Preview for Developers to get Cyan Update ?
If you are in a hurry to update to cyan you have to downgrade. If you can wait for some time, MS may roll out in the near future as some report the update is resuming for dp users too. But it has been in a small scale so far
