Hey, so I have a Samsung Galaxy S3 on At&t and I'm looking to upgrade it to Jelly Bean. As far as I know, the only way to do that is through Kies on the computer. I've read that that a box will open up letting you know that you can update and from there on you just accept and update it. So I downloaded Kies, plugged in my phone and nothing happened. I'm not really sure what to do beyond that. I don't want to root my phone or anything like that. What do I need to do in order to get the Jelly Bean update? Thank you and happy holidays!
