Re: Is this Cyan?
Today's update may be cyan for you. I did the NSRT and updated my 920 on ATT to cyan when they released it, killing my game progress, then reapplied DP.
Just now, I installed today's update on my 920, already running cyan. BUT I also ran update on my daughter's 920, which had been DP on black. Same amount of time to update both phones... and she now has cyan!
So if you have a 920 on ATT, it is very likely you're getting cyan today. Be sure to run a backup before you start the update... just in case.
