Apple just released the latest iOS 13 beta version which contains an unexpected gem: the actual 2019 iPhone keynote date. That’s September 10th, just as we suspected, although the iPhone maker is yet to issue invites for the press conference. If that date turns out to be accurate, we’d expect preorders to kick-off around the world on September 13th, precisely one week before the iPhone 11’s in-store launch/ship date. It turns out, however, that individual carriers have already opened up iPhone 11 reservations, offering buyers early deliveries.
