Following reports that the iPhone 5se and iPad Air 3 will be unveiled on March 15, it now appears that the models will also be available in Apple Stores three days later, on March 18, according to a new report from 9to5Mac. With the devices going on sale so soon after the event, sources suggest that Apple is unlikely to offer pre-orders for either of the new devices, although they cautioned that Apple’s plans could still change. In the case of iPhones, in particular, Apple has traditionally opened pre-orders within two to three days after it unveils a new model, with in-store availability coming one to two weeks later, around the same time pre-orders begin arriving in customers’ hands. While Apple’s iPad releases have been a little less consistent in this regard, it would still be unusual for Apple to release both devices in-store so quickly following a major Apple event. Sources have suggested that Apple has already begun ramping up production of the new four-inch iPhone, which is intended to bring the latest technology — specifically NFC for Apple Pay — to the iPhone 5 family for users who may be reluctant to embrace the larger iPhone 6 screen sizes.
