Apple Begins Sales of the iPhone Duo, Its First Foldable iPhone

Overview

• Sales started Friday, Oct. 23, with stores and major carriers receiving very small first shipments that prompted operators to offer steep discounts and long financing to meet strong demand.
• The Duo pairs a 7.6-inch internal display with a 5.4-inch external screen, runs on the A20 Pro chip, uses a dual‑battery design and includes two 48MP rear cameras plus fold‑specific camera modes such as Duo Preview and Duo FaceTime.
• Apple adapted iOS 27 for the foldable with split‑screen, dynamic UI adjustments, a split keyboard and saved app layouts, but reviewers and developers say many third‑party apps still need updates to work well with the Duo’s unusual aspect ratios.
• In Brazil the phone starts at R$21,999 for 256 GB and reaches R$30,999 for 2 TB, though carrier plans cut prices to about R$17,000–R$18,000 under contract and some operators reported receiving roughly 100 units each in the first allocation.
• Early reviews praise the Duo’s materials, hinge and display but call it a first‑generation product that requires time for software and app ecosystems to catch up, meaning broad consumer adoption will depend on wider availability and developer support.
