I just unrooted and returned to stock; FYI, it's a PITA if you are using custom roms.
You have to unroot; then flash the right modem; then Kies will pick up the phone and do it's update.
I'm curious to see if the "actual" AT&T rom is better in terms of battery over custom roms. I don't mind the custom, just wish someone would release a plain jane like the Galaxy Nexus had from Google. I don't want anyone's stupid attempts at graphics, etc.
Anyways, to confirm, I too am getting ICS off of Kies right now.
What do you mean flash the right modem then Kies will pick up the phone. What was the issue, Kies not finding your phone or not updating the phone. I flashed back to stock (was using Objection rom)m and now I'm getting "Your device does not support software upgrading via Kies" or do I have a different issue.
EDIT Nevermind, just followed the steps here:
[REF] Recover AT&T Note to GB Factory with Kies (Will NOT trip your flash counter!!) - xda-developers
I was running Objection RC1,
1. Flashed back to stock w/Odin
2. Reflashed CWM
3. Flashed the flash counter reset (3 times)
4. Flashed the stock recovery
5. Did a factory reset three times
6. Verified counter was 0 and I was on the official binary
Well when I plugged my phone into Kies I got an error that said "Your device does not support software upgrading via Kies" So I then followed the 1st post at XDA and after a heart pounding 10 minutes (the status bar was moving along then for no reason during the flash reset once to 0% starting over) but I just left it alone and walked away. BTY it 1st downloads the firmware, resets to 0, then flashes the firmware, that is what I saw reset the status bar.
I am now running the official 4.04 UCLF6 ICS

I was just able to update my wife's skyrocket as well. She does not know it yet since she is asleep but she will in the morning
