Apple is preparing a three-year plan to reinvent its iPhone lineup, beginning with the launch of the iPhone Air this fall, followed by a foldable iPhone in 2026, and culminating with the 20th anniversary iPhone in 2027. The foldable iPhone, expected to debut in 2026, will feature a book-style design with four cameras, Touch ID instead of Face ID, and an in-house Apple cellular modem known as the C2 modem. This model marks the return of Touch ID to the iPhone series. The 2027 iPhone 20 is anticipated to incorporate a curved-glass design and could benefit from advanced display technology, specifically a Tandem OLED panel developed by LG Display, which Apple has previously helped pioneer with the M4 iPad Pro. The introduction of the foldable iPhone may delay the base model of the iPhone 18 to 2027, although higher-end iPhone 18 models are still expected in 2026. These developments indicate Apple's strategic shift toward innovative form factors and enhanced display technologies in its flagship smartphone line over the next few years.
