Part of the problem is probably that Jelly Bean hasn't even been released yet. We can't give Pioneer's devs *too* much crap until it's official for our Galaxy Nexi next week (hopefully). Although I'm on Verizon so without flashing it, it might be even longer...
Now with CM9 only getting to a stable release before jumping straight into CM10, Idk if I'll flash CM9 like I've been planning, or flash a stock rooted Jelly Bean Toro image...
