I’m sorry if this has already been asked but when is the public release of 5.1 expected to be available?
If it keeps on track with the x.1 release schedules from the past couple of years, then it'll be about another week, give or take. This would also land it in between the pre-order date and release date for the iPhone XR, which makes sense, as I'd imagine they'd want to ship the iPhone XR with iOS 12.1.
But of course this is all just guessing. No one here knows for sure. The only people who have that info are at Cupertino.
