Apple will have limited iPhone Duo units available in stores on Friday

Apple will have a limited supply of its new folding iPhone Duo available for walk-in customers in stores on Friday, following strong online demand that quickly sold out initial orders and extended delivery times for some to January. The iPhone Duo, announced in September, marks Apple's entry into the folding phone market, a segment where competitors like Samsung and Huawei have been present for years. Analysts suggest that the device's complex hinge mechanism may pose manufacturing challenges for Apple in achieving high-volume production. While walk-in availability for the iPhone Duo will be limited in the United States, Australia, Canada, Mexico, and parts of the UK and Europe, other regions including mainland China, India, Japan, and South Korea will only offer units for online order pickups. Uniquely, Macau will have limited walk-in availability as the only purchasing option. This launch is significant as it introduces a new product category for Apple, potentially reshaping a niche premium smartphone market.
