The option to reserve an iPhone Duo for Apple Store pickup is slowly returning online in select countries like Australia and Japan. However, current availability is extremely limited, with almost no time slots or units discoverable. For example, a single unit found in Australia quickly vanished before publication. Other regions like the U.S. and U.K. are expected to reactivate the reservation system on Saturday, October 24. This scarcity is attributed to "extraordinary" demand since pre-orders began, pushing delivery estimates into late January. Apple previously offered store pickup briefly after pre-orders but quickly disabled it. The high demand led to long queues at Apple Stores for walk-in purchases. For those unable to secure a device, the online store pickup tool remains a viable option. Customers are advised to monitor the iPhone Duo order page frequently for updates. Apple is actively working to fulfill demand as quickly as possible. The iPhone Duo remains a highly sought-after device.
