I tried booking an upgrade appointment back in early May when it was confirmed they were being installed in Model 3s. After some initial confusion about what I was asking for, mobile service canceled my appointment saying that while initial releases are already rolling out, my VIN range wouldn't be ready for about 4 to 6 weeks and that they'll notify me when ready.
Since then, I've heard of nobody getting the upgrade. That said, it is now past the 6 week mark, so it is possible OP may be one of the first to actually get it. I went ahead and booked another mobile service appointment today (also for the 25th) to see if I can get it installed too as I have texts from the local mobile service folks saying it'd be ready around now. We'll see what happens. Like most of you, I expect this one will get canceled too.
Here's a screenshot of the end of my conversation w/ mobile service from back in May:
