Wanda, I'm going to Root mine this coming weekend. What are you using? Any issues with it?
I just restored my nand of ViperREZ after giving Newt's ICS/JB hybrid a run for the past two days. Its a good ROM (the hybrid one) with only a few minor issues. I came back to the other because I'm about to hit the road for 4 days and I need the proven reliability of my trusty old ViperREZ.
I've also run just about all of Neo's AOSP/AOKP JB based roms (and theres a lot of them) and in my opinion his TRON is a very solid JB based AOSP rom. If this is you're first time coming from stock ICS with Sense 3.6 I'd say start with ViperREZ. Its going to be a lot more familiar to you being that it's Sensed 4 based. Its also rock solid and is VERY customizable through the Venom HUB and Venom Tweaks. If you're feeling really sporty I'd definitly try TRON but I did notice that AOSP roms always seem to partition (not sure if thats the right term for it) my SD card differently. What I mean is, my titanium backups that are on my external SD didn't restore, I had to copy them to the internal SD to get it to work right...and the way it "orginizes" photo's is mildly annoying to me as well. Just minor stuff though. Go ahead and dive in! After you've made a Nandroid backup of course.
Can't wait for my wife's Thunderbolt to get ICS; still digging my Rezound... even with the Quasimodo hump from the 2750 battery.
I'm about two steps from joining you on the Quasimodo tip. Today I was down to 9% by 1530, though I did come off charger at 0545.
