The Full 2027 iPhone Roadmap Under Ternus
Apple’s 2027 Product Lineup:
“Apple plans to introduce its first foldable smartphone later this year and is developing a 20th anniversary iPhone for 2027”.

Why This Design Shift Matters
Historical Significance:

The Bottom Line
Apple is preparing the “biggest set of iPhone revamps in the product’s history” under hardware engineering chief John Ternus, who is widely considered the leading candidate to become Apple’s next CEO when Tim Cook steps down in September 2026. The centerpiece is an ambitious 20th-anniversary iPhone expected in fall 2027 featuring a true edge-to-edge design with no cutouts in the display, a curved glass enclosure, and the front camera located under the screen. The device will feature a “Waterfall display” curving along all four edges, making a sweeping change from the flat front design that has defined iPhones for nearly 20 years. Two versions are expected: iPhone 20 Pro and iPhone 20 Pro Max, launching alongside a second-generation foldable iPhone. The 2027 anniversary event is expected to be Ternus’s first major product launch as Apple’s global leader. This represents the most significant hardware redesign since iPhone X and part of a three-year plan to reinvent the iPhone form factor. Ternus’s roadmap also includes AI-native hardware like camera AirPods and smart glasses, betting the company’s next decade on this direction. The original iPhone was unveiled in January 2007, making 2027 the device’s 20th anniversary.
