iPhone Duo jailbroken on launch day by security firm Calif, MacRumors reports
Security researchers say they have jailbroken the iPhone Duo within hours of its release, according to a report from MacRumors citing the German outlet Heise.
The group, a security firm called Calif, showed an iPhone Duo running iOS 27.1 with its home screen icons and widgets moved around and an anime character added to the display. Stefan Esser, a researcher speaking to Heise, said the team had achieved the result on launch day. The MacRumors report does not say which chip the device uses or detail the exploit chain used on the Duo.
