That's the best part of the pre-approval process. You have a pretty good idea of which phone you are going to get. If there's a sim-free unlocked version, you'll know after tomorrow.Apple offered SIM Free for the Xs and Xs Max last year on release its what I got. They didn't for a bit on the Xr though. If your getting an 11 Pro it will likely be available day 1. You will be able to see this tomorrow after the keynote when the site updates what the options will be.
