iPhone Duo preorders are now live: Everything you need to know before buying Apples first foldable

It's almost iPhone Duo day, folks.

Announced in September after years of rumors, Apple's first-ever foldable phone is now available for preorder ahead of its Oct.

23 release.

The iPhone Duo features a passport-style design with a nano-texture inner display, a hidden selfie camera, a blazing-fast A20 Pro chip , and a hinge with a flexible graphite pipe inside — its secret to effective cooling.

Mashable senior editor Stan Schroeder got to spend a little time with the Duo at Apple Park last month and said it "works amazingly well." (Our full review is coming soon.) If you have any questions before preordering the iPhone Duo, we're got all the answers.
