As of Thursday, October 29, no iPhone Duo configuration was available for pickup at any of the 162 U.S. Apple Stores we checked across 16 major metro areas, but it's worth checking pickup availability often on Apple's iPhone Duo order page in case small quantities of inventory become available. Apple's online stores currently quote shipping in late January 2027 for all iPhone Duo configurations, though Apple said earlier this month that it is working to satisfy demand "as quickly as possible," and some pre-order customers have already seen their estimates move up.Related Roundup: iPhone DuoBuyer's Guide: iPhone Duo (Buy Now)Related Forum: iPhoneThis article, "Just Got an iPhone Duo?
