Everything about the iPhone Duo, in one place
An independent guide to buying, using and caring for Apple's first foldable iPhone.
01
The complete, independent guide to owning an iPhone Duo
iPhone Duo Guide exists to answer every question an iPhone Duo buyer or owner has: which storage tier and color to choose, where to find stock, which cases and apps work with the folding display, how to care for the hinge and screen, and what Apple's service options cost. Our objective is to be the most comprehensive source of iPhone Duo information online, drawing on Apple's documentation, published reporting and the experience of owners, with our own hands-on notes added and labeled as we use the phone.
iPhone Duo Guide is an independent site and is not affiliated with, endorsed by or sponsored by Apple Inc. When something is confirmed by Apple we say so; when it's a report or a rumor, we label it.
