Yes I am running blurry maxx and 4.2 works great on it. As for that kill ROM, I have not tried it but it looks like it is a beta build so 4.2 camera may not work on it anyway.
Thanks for the info DD & dd --Yes, it certainly is beta and I did flash it after a full wipe -- there's a few other issues that I'm having with it, so it sounds like Blurry Maxx is a good candidate for next flash.
Yes it is. Blurry max is my favorite ROM by far . and I have tried every single one. Except for the beta killer ROM you just tried. Everything is fully functional on blurry maxx. There are tons of wallpapers and ringtones and notifications. Animations are wicked cool too. Its over clocked with excellent battery life. All around great ROM.
