Only AT&T knows for sure. I'd suggest calling their customer service/tech support line.Im trying to download the 4.3 on my s4 and it still says software is up to date. Are there still regions where this update isnt available?
Im in New Jersey
Thanks

Not sure why so many people are having issues with 4.3 on their S4 but for me I have no issues whatsoever on my S4 and currently on 4.3.
