I got the update pushed to the phone I did not have to force it..
Fast update, had issues.. It would not work so contacted ATT via chat and they had me reset network setting and put phone in airplane mode to test it.. I can now text pictures from inside my house and I'm hoping to make calls and not drop them after 2 min. I was going to Verizon because Att did not have wifi on the S6.. I have a microcell and that would not let me send pics via texts.. And I was having issues with it starting to drop calls.. Glad this update came..
