What exactly are you looking for? It runs ICS already (at least, mine did). What version is yours running now?
Also, what do you see when you run Hardware Info (or other hardware apps)? I was told it's a 1.5GHz CPU, but mine reports 1GHz. SetCPU (and similar apps) show 1GHz is the max as well so I can't really overclock it...
I've been looking for anyone who is doing a JB ROM for it, but no luck so far.
