I wasn't lying. When I posted that, 6.0 came up as being available in my area. But, I suspected that it was an error on BS's end. So, I waited a few days and checked again. That's when I saw it was removed. I think once BS is ready for a wide-range rollout it will reappear. I'll sign up then.
I had to go in through the BS "catalog," since the main listing of FastAccess services doesn't list Xtreme 6.0 yet. I clicked this link
