Look up. Links to info are there and you can manually try to update. If it just started rolling out it doesn't mean you will get it right away.
It was JUST announced on this forum by someone who follows this news closely. It will take time to get to everyone. No way Verizon could handle everyone tapping the "update now" button at the same time.
And, word of caution, take some time, about 2 weeks for the praises or complaints to start rolling into the forum before updating. I reference the Galaxy S5 fiasco.
