I'll have to say when I first delved into how to do this, I was pretty intimidated. But my frustrations with KK spurred me to act. As a newbie, I only felt comfortable to proceed after a lot of reading. In the end, it wasn't too complex.
Next step for me is to return to JB. My phone functioned much better on that OS.
Yea, that's what I wound up doing, too. Check out the Validus JB ROM.
It's pretty awesome and bug free.
