This Friday, June 29, at 6:00 pm local time, the revolutionary iPhone goes on sale at the 164 Apple retail stores nationwide, all of which will stay open until midnight. Customers can purchase up to two iPhones on a first-come, first-served basis. Beginning Saturday morning, all Apple retail stores will offer free, in-depth workshops, so customers can learn how to get the most out of their new iPhones. They’ll also have access to free iPhone support at the Genius Bar and personal training through Apple’s new One to One program.
