They guy I bought the car from said that he signed up to be a beta tester when he got the car. Also Tesla is picking up my car in 30 min and I asked them to pull 6.1 and they said no can do which I found odd.
My SC told me they could not install, and that has been reported by many owners. They won't/can't. Reports indicate that different Service Centers have given vastly different explanations. I'd take all of the explanations with a grain of salt... clear message is they won't be doing this any more.
