Apple sells out iPhone Duo in stores as foldable launch draws global demand

Apple Inc. sold out of its limited in-store inventory for the new iPhone Duo on Friday, highlighting strong demand for its first foldable device, which starts at nearly $2,000. The launch drew overnight lines from New York to Singapore, with stores receiving roughly 50 to 200-plus units each. Popular configurations sold out within hours, and new online orders face delivery delays until late January, marking some of the longest waits for an Apple product. The Duo, priced up to $3,199, represents Apple's biggest design change in the iPhone's history. It arrives amid industry-wide price increases and limited production due to advanced hinge technology, with competitors like Samsung also raising prices.
