iPhone Duo Jailbroken on Launch Day

Just hours after being released, an iPhone Duo running iOS 27.1 has been jailbroken by hacker team Calif.

iPhone Duo AAAAAAAHHHHHPP Icons Feature
Calif demonstrated the ‌iPhone Duo‌'s icons and widgets bouncing around, and added an anime character to the device's screen.

Last week, the group shared videos featuring an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1. The device was shown rebooting, with root access available after the reboot.


Calif has not publicly released the jailbreak. Calif security researcher Stefan Esser told German site Heise that there won't be a jailbreak tool available for "end users," but a proof of concept may be forthcoming.

Esser said the iOS 27.0.1 jailbreak used bugs Calif has already disclosed or plans to disclose to Apple soon, and "most" of the vulnerabilities are fixed in the upcoming iOS 27.2 update. AI was used to help develop the jailbreak, but Esser didn't explain how.

Friday October 23, 2026 11:05 am PDT by
Some iPhone Duos are already experiencing hinge issues that cause display cracks, based on photos shared on Reddit and the MacRumors forums.

Hopefully Apple will provide that Home screen layout in the next iOS version. Call it Liquid Layout.

I wouldn't be surprised if the vulnerability was obscure, but allowed.

The duo/folding concept needs a lot of real-world input in order to truly get right. Apple could be looking for that.

Anyway, how nice to link back to the good old days when jailbreaking was worthwhile and really provided a solid user experience upgrade over Apple's offerings.
It really is amazing how many iOS features we now have started out as Jailbreak tweaks.
