Galaxy s3 android update to 4.3

Got on my S3 and went to the Update setting just for the heck of it, and it said I have an Update. So downloading it now here in Tn.  Can tell it is very Slow 623.10MB to download.

Yep mine in Tn. is downloading now. 623.10MB seems very SLOW download.

I just saw that myself I can't believe it I am downloading it now it looks at it will take 20 minutes to download.  I am 14 minutes into it and I am at 48 percent. Will give another update soon. 

My phone said that update is suspended and i need to try in next 48 hours.. I think ATT phone are getting worse and wors same as ATT with all not caring about what customers want..

I think ATT is so small company they can not handle more then 1 update on time... They always sucks that why i'm thinking to change provider as soon as my contract expire.

ok download of the update was about 30 minutes adn updating was about 15 minutes it almost looks like the phone bricks at certain points but just letting it do the update it came up no problem.  It does seem quicker and the settings meu has changed and the mobile data butto is gone.  It does have knox but haven't been able to see how to access the app also lookout antivirus is not part of the update as far as I can see.

I was able to download the update in 30 minutes this morning and no problems it did take about 15 minutes to go through the update and it seemed like it was going to brick but just let it do its thing and now its running just fine still going through the menus no battery drain issues so far and it is charging with no problems. When I did the update I was righ next to my wireless router and it was pretty quick in downloading.  

My download started, but then it stopped.  When I go to check for update, I get told I can't for another 13 hours.

Is there anywhere on the phone that I can start the update again?
