Is iPhone Duo official?
Yes. Apple announced iPhone Duo on September 9, 2026. The manufacturer’s press release and store listing now identify the product directly.
What is different about it?
It folds shut for use on an outer screen and opens into a wider workspace. The official introduction film demonstrates the design. For measured size, camera configuration and charging requirements, use our specifications page.
What happened to iPhone Fold and iPhone Ultra?
Those names appeared in pre-announcement coverage. They are useful historical search terms, but they do not identify additional models in the Duo announcement. Renaming an old rumor article does not validate its old numbers.
Does Duo mean an entry-level foldable?
The name alone does not establish a tier. The sources checked for this update show one named Duo model with different storage options, not an announced Duo Pro or Duo Ultra lineup. Do not assume unannounced models or a lower-cost version exist.
Where should I start?
Use prices by capacity, release dates and the buying guide. This website is an independent reference, not an Apple store or an official support channel.
