iPhone Duo: The 5 most important things you need to know

$1,999, two colors, mid-October

As expected, the iPhone Duo is about twice the price of an iPhone 17 Pro. The starting price is $1,999 with 256GB of storage, which is actually on the lower side of the rumors. Adding more storage inflates the price, with options up to 2 terabytes for $3,199.

Preorders start on October 16, and the iPhone Duo goes on sale on October 23.

There are two colors available: Star White and Night Sky. These are very similar to the Silver and Midnight colors we’ve seen in previous Apple products.

It’s all about flexibility

One thing the rumors didn’t pick up on: Both the inner and outer displays have the same aspect ratio: 1:1.4. That makes the outer display exactly one half of the inner display, and Apple uses this symmetry, along with a lot of orientation sensing, to alter the way iOS works.

Currently, many iOS apps, and the operating system itself, do not adjust to multiple orientations. With the Duo, Apple has updated its own apps to work in portrait or landscape, and even behave differently depending on whether they’re on the outside or inside screen.

The Dock now runs up the side of the screen, allowing more vertical room for the Home Screen, and the inside display simply shows two home screens at once. Most app toolbars and controls are also now on the side edge, along with a new more compact status icon area.
