The iPhone Duo ships with iOS 27.1, a version of iOS 27 exclusive to the foldable device. Apple yesterday released a new build of iOS 27.1 (24A94425), which means buyers will have a day-one software update to install.
The iPhone Duo is shipping with iOS 27.1 build 24A94232, and if it's not already in the hands of reviewers, it will be soon. Apple likely released the new build to address bugs while the Duo is being evaluated by members of the media.
Since the iPhone Duo isn't coming out until October 23, there's plenty of time for Apple to release another iOS 27.1 update or even iOS 27.2. Buyers might not have the 24A94425 update to install if it's replaced by something newer, but either way, there will be an update required during the iPhone Duo setup process.
Pre-orders for the iPhone Duo begin on Friday, October 16, at 5 a.m. Pacific Time or 8 a.m. Eastern Time. It will launch on Friday, October 23.
If you're planning to pre-order the iPhone Duo, you can use Apple's Get Ready process to select a color and capacity, as well as confirm carrier status, choose accessories, and supply billing information and payment. Get Ready speeds up pre-ordering, and it is recommended given the expectation of supply constraints.
