Read official post here. This only leads to more confusion:
"However, we will give the opportunity for Kickstarter Backers to upgrade very soon, for a limited time. This upgrade ability for Kickstarter Backers will be available a week after we received their answer from the Kickstarter Survey"
According to that statement, should have been live. I received my Survey and answered. Since I now have a Gold symbol, I know they received it.
