It does have the gem all over it. Last page, a couple pics, and an explanation of it. It has Sapphire on it. Not Cyanogen. It was originally made for CM. It wouldn't be "Watermark'D" unless it had the ROM logo.
But I have one big question concerning the notification pulldown being so dark... how should I deal with certain apps that suddenly won't respond to Gem text color settings? For example, Weather Bug and SipDroid... both seem to be stuck with black, unreadable, text. I sure hope I am just missing sosomething obvious.
