    If my Lumia 920 using the Windows Phone 8.1 Developer Preview, should I need to update to the Official Update of Lumia Cyan before I want to update to Windows Phone 8.1 Update 1?

    Short answer: Nope

    Lumia Black/Cyan/whatever is a separate entity from Windows Phone 8, 8.1, 8.1 U1 but they are typically distributed together.

    no... it is just a firmware update, and you can install it whenever you want (it also download windows phone 8.1 (update 0/original) if your current OS is lower than the OS it download)

    Same for me this morning. After the update I looked to see if I was still running DP & I was. Still had the box ticked.
    I would say it was official.
