Earlier today found our S3 downloading a large update (via WiFi)--THEN it asked if you wanted to continue. You'd think they'd ask BEFORE such a long download. Anyway turned out to be 4.1.1. I thought AT&T had decided to only make it available via Kies--which I don't use for syncing so hadn't got round to setting it up just for the update. Now I don't have to. Didn't even have to do a manual check for updates. Everything looks good for now. Guess time will tell if I need to do a factory reset.
