Nothing here in New England. My sgs3 is rooted running clean rom, but the wife's is stock and I have to keep sneaking a check on the update every time she puts it down.
From what I have read, the OTA will go out for at least a week. Then the update will be available to be pulled manually then. So all of us will be waiting in batches. Me? I will wait as patiently as I can. But I can tell by taking the temperature of the forum, the tension is tight. I can just imagine how much more efficient the phone will be after the update.
