The option to reserve an iPhone Duo for Apple Store pickup resumed in the U.S. and Canada between 5:10 a.m. and 5:15 a.m. Pacific Time today, but inventory is extremely limited, with most stores having no pickup slots available today. You can search for iPhone Duo availability at your local App le Stores by heading to the iPhone Duo order page, selecting your desired color and storage and so forth, and then opening the link next to the "Pickup" option at the bottom. Next, enter your ZIP code and you will be able to see if any models are available for pickup with a reserved time slot. Apple Store pickup was offered for just a few minutes after iPhone Duo pre-orders began on Friday, October 16, and the option then disappeared until now. Just hours after iPhone Duo pre-orders began last week, Apple said demand for the device was "nothing short of extraordinary," with delivery estimates pushing into late January, so it is not surprising that Apple Store pickup slots are hard to come by right now. Apple said it is working to satisfy demand "as quickly as possible." Given the scarcity, long queues formed at many Apple Stores around the world on Friday, with some lucky customers managing to secure an iPhone Duo on a walk-in basis. If you are still looking for an iPhone Duo, check Apple's pickup tool often.Related Roundup: iPhone DuoTag: Apple StoreBuyer's Guide: iPhone Duo (Buy Now)Related Forum: iPhoneThis article, "Apple Store Pickup System for iPhone Duo Just Went Live Again in U.S. and Canada" first appeared on MacRumors.comDiscuss this article in our forums ...read more read less
