Pre-order supplies of the iPhone 7 and the iPhone 7 Plus are starting to dwindle, with several of the new iPhone models now displaying shipping estimates ranging into November. Pre-orders began at 12:01 a.m. Pacific Time on Friday, September 9, and it took less than 20 minutes for supplies of popular models to begin selling out.
Mine says Sept. 23rd for the 256gb black. In my experience from the last 3 releases if your order says its within the month, it's going to ship on the release date anyways.
