Apple’s iPhone Duo Case Requires Adhesive, Launch Faces Shortage

Apple’s first foldable phone, the iPhone Duo, comes with two official accessories: a $79 silicone case and a $129 folio case. The silicone case uses adhesive that must be exposed before it can stick to the phone. Users who have bought the case report that it will fall off if the adhesive is not applied.

Adhesive Requirement for Official Silicone Case

Because the adhesive is on the inside of the case, customers must carefully peel away a protective layer before attaching the case. If the adhesive is ignored, the case can detach easily, limiting the ability to swap cases or go caseless. Third‑party cases that don’t require adhesive are available.

Apple Retail staff have been told to warn customers that the iPhone Duo will not be available for walk‑in purchase on launch day. The company has limited production, with only a few hundred units per day in late August, and pre‑orders have pushed delivery dates beyond January. The online store shows all configurations set for January 25 shipping, and the device is effectively sold out for Christmas.

Apple has described the pre‑order demand as “nothing short of extraordinary.” The first deliveries are scheduled for October 23, but shipment dates have been pushed to December and then to January 27, 2027, with the possibility of further delays. The statement says the company is working hard to get the product into customers’ hands as quickly as possible.
