Is a foldable iPhone available to pre-order by 18 September?

Eight of the last eight base flagship iPhones were in Apple stores by the second Friday after the keynote, never more than eleven days. Across all fourteen September-cycle launches since 2012 it is thirteen of fourteen; the exception is 2015, when the iPhone 6s took sixteen days. The 2020 event slipped to October but the phone still shipped in ten days. New shapes have run slower: the iPhone X took 52 days in 2017, the XR 44 days in 2018 and the 14 Plus 30 days in 2022.
