Apple's first foldable handset, the iPhone Duo, reached customers today, with actual delivery timing varying based on when buyers placed their pre-orders. Alongside the device, Apple pushed a same-day software update exclusive to the new model, addressing early bug fixes before the phone has even settled into widespread use.
A device-specific update arrives immediately
The iPhone Duo ships with iOS 27.1 pre-installed, but Apple issued a fresh build of that same version on launch day. The release notes describe only general bug fixes, without mentioning any security patches. Notably, iOS 27.1 has not been tested through public or developer betas and is currently limited to the Duo alone - other iPhone models remain on iOS 27.0.1, released last month.
This divergence means Apple is managing two separate software tracks simultaneously: one for its existing iPhone lineup and another tailored to the foldable's distinct hardware, which likely requires adjustments for its hinge mechanism, dual-screen behavior, and folding display calibration.
What happens next for other iPhones
Apple is already testing iOS 27.2 for the broader iPhone lineup, with a public release expected next week or in early November. Rather than receiving iOS 27.1, non-Duo iPhones are expected to jump straight from 27.0.1 to 27.2, effectively skipping the version built specifically for the foldable. This suggests iOS 27.1 was never intended as a general release, but rather a launch-focused build to stabilize the Duo's debut.
Pricing and configurations
The iPhone Duo starts at $1,999 for the 256GB configuration, climbing to $2,199 for 512GB, $2,599 for 1TB, and $3,199 for the top 2TB tier. Buyers can choose between two finishes: Star White and Night Sky. The pricing places the Duo firmly in premium territory, well above Apple's standard iPhone range, reflecting the added engineering complexity of a folding form factor.
- 256GB: $1,999
- 512GB: $2,199
- 1TB: $2,599
- 2TB: $3,199
What it means for early adopters
For buyers who secured a pre-order early, today marks the actual start of hands-on use, including an immediate software update before the device even leaves its initial setup screen. Those still waiting on fulfillment will likely receive units already running the updated 27.1 build. As with most first-generation hardware, early software patches of this kind are common and typically address device-specific quirks discovered only after broader real-world use begins.
