What OS version is cyan

[WPCentral Question]

I have a lumia 620 with OS 8.10.12393.890 - is this cyan?

Cyan is not just OS but the firmware along with it.
But in essence ur current version is the WP 8.1 which is supposed to come along with cyan unless u have enrolled to the preview and got it.
Just check extras+info and see.
