Mark Gurman, reporting for 9 to 5 Mac:
Apple is currently on target to start selling its next iPhone and iPad models the same week that the new products are introduced in March. Apple is currently planning to introduce a new 4-inch iPhone dubbed the “iPhone 5se” and a new iPad Air at an event on Tuesday, March 15th, then put the products up for sale online and in retail stores as early as Friday, March 18th, according to sources. Apple is unlikely to offer pre-orders for the new devices, according to sources who cautioned that the plans could still change.
4-inch iPhone enthusiasts, you likely have just five weeks to get your finances in order.
