The iPhone 16e just launched, but Apple has four more iPhone models launching this fallincluding the ultra-thin iPhone 17 Air. But per Mark Gurman, 2026 may be even bigger for the iPhone thanks to two brand new designs in the works: a foldable and another mysterious new design.Next years iPhone lineup could bring two brand new designsThis weekend in his Power On newsletter, Mark Gurman detailed Apples current iPhone plans for this year and next. And its what he shared about next year that was especially interesting.Gurman writes at Bloomberg:[Apple is] readying a skinnier iPhone for later this year and focused on finishing up development of its first foldable device for 2026. Theres also another new iPhone design in the works for that year, Im told.There are two significant details worth noting here:Apples foldable iPhone is still expected for 2026 and nearing the end of developmentand also, a second iPhone next year will come with a new designThis is the first weve heard of two new iPhone designs in 2026.Its especially surprising, too, since Apple plans to launch the new 17 Air design this year, plus some noteworthy design changes to the iPhone 17 Pro models.Gurman doesnt go into any details on this second new iPhone design, but it will be fascinating to see what Apples plans are as more information is revealed in the future.Perhaps the base model iPhone 18 will get that new design, since its the only model not changing much in the iPhone 17 lineup. Then again, Gurmans wording seems to hint at something more substantial than a base model revision.Apples 2026 iPhone lineup is still a ways off, but these rumors definitely seem to support recent teases from CEO Tim Cook and hardware chief John Ternus that their iPhone roadmap is more ambitious than ever.What do you think this mystery new iPhone design in 2026 might be?
