windows 8.1 update for Samsung ATIV S (GT-I8750)?

I purchased a Samsung ATIV S (model GT-I8750) from Amazon.com several months ago...to date I've not received any software update to bring the phone up to Windows Phone 8.1.
Can anyone share provide a solution?

There seems to be a lot of Ativ S variants and no centralized place to check easily... You may want to reda more in the Ativ S forum: Samsung ATIV S - Windows Central Forums
