Apple's first foldable iPhone Duo opens preorders, starting at $1,999

The iPhone Duo is Apple's first foldable phone, unveiled alongside the iPhone 18 Pro, Apple Watch Series 12 and Ultra 4 at the "Surprise and shine" event. It has a 5.4-inch outer display and unfolds to a 7.6-inch Super Retina XDR screen, with Apple Pencil support coming later this year. The side holds a Touch ID sensor, with no Face ID; it's IP68-rated, with Ceramic Shield 2 on the back and Ceramic Shield on the front. It shares the A20 Pro chip and 48MP Fusion camera with the iPhone 18 Pro, but lacks a variable aperture. It comes in Star White and Night Sky, starting at $1,999 for 256GB. Unlocked preorders are open at Apple and Best Buy, with release on Friday, October 23. Carrier buyers should compare: AT&T offers up to $1,200 for eligible trade-ins via 36 monthly bill credits, plus up to $800 on a reward card to pay off an old device for switchers; T-Mobile offers up to $1,000 trade-in on Experience Beyond or Go5G Next plans, or the same value without a trade-in when switching and adding a line; Verizon waives the $40 activation fee, offers 0% financing over 36 months at $55.55/month, and a $72.22/month Simplicity Pro plan with two extra TravelPass days monthly and up to two upgrades in a rolling 12 months.
