This might've been posted earlier, but I remember some people were worried about Apple maybe sending Jet Black iPhones to retail stores, thus making some people who got in on the pre-order wait longer. Apple had a statement saying that 7+ and Jet Black 7 and 7+ will not be available for walk-in orders at their retail stores.
"We couldn’t be happier with the initial response to iPhone 7 and iPhone 7 Plus, and we are looking forward to beginning sales through our retail stores and partners around the world.
Beginning Friday, limited quantities of iPhone 7 in silver, gold, rose gold, and black will be available for walk-in customers at Apple retail stores. During the online pre-order period, initial quantities of iPhone 7 Plus in all finishes and iPhone 7 in jet black sold out and will not be available for walk-in customers. Availability at partner locations for all finishes may vary and we recommend checking directly with them.
Customers can continue to order all models in all colors on apple.com. We sincerely appreciate our customers’ patience as we work hard to get the new iPhone into the hands of everyone who wants one as quickly as possible."
