The Apple Store pickup system for iPhone Duo resumed in the U.S. and Canada early Friday morning, but inventory is extremely limited, with most stores reporting no available slots. Apple Store pickup had briefly returned after initial pre-orders launched on October 16 but vanished again. Demand has been described as "nothing short of extraordinary," with delivery estimates pushed into late January.
Long queues formed at Apple Stores globally on launch day, Friday October 23, as some customers secured units via walk-in purchases. Apple retail staff have been instructed to discourage walk-in attempts due to expected stock shortages. Those still seeking iPhone Duo availability should monitor Apple's pickup tool frequently, as slots are released sporadically and sell out rapidly.
