The group also shared footage of an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1. Untethered means the modification survives a restart. The device was shown rebooting, with root access (full administrator control of the system) available afterward.\n\nCalif has not publicly released the jailbreak. Stefan Esser, a Calif security researcher, told the German tech outlet Heise that there will be no jailbreak tool for \"end users,\" but that a proof of concept may follow. A proof of concept is a demonstration that a flaw works, not a polished app anyone can run.\n\nThe two demos are not the same thing. The Duo footage is visual: it shows Calif can change what appears on screen. The reboot and root access demonstration involved a different phone and an earlier version of iOS. Calif has not said whether one flaw sits behind both, or whether the iOS 27.1 result goes as deep as the 27.0.1 one.\n\nThat gap matters because jailbreaking has long served two audiences: hobbyists who want to customize their phones, and researchers who want to inspect how the system works. Withholding a public tool puts this release firmly in the second camp. For Duo buyers, the practical risk is limited for now, since nothing is available to run. The open question is what happens once details do surface, and Calif has not said whether it has shared them with Apple.","[\"jailbreak\",\"iphone-duo\",\"ios-27\",\"calif\"]","2026-10-23T19:41:05.000Z","2026-10-23T19:55:32.843Z","2026-10-23T19:55:33.152Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Name the German outlet (Heise) instead of 'a German tech site', and replace 'Nothing in the material says...' with plain reader-facing wording (e.g. 'Calif has not said whether...'), since it reads like a process note and implies a partial source; also tie the October 23 date to Calif's post rather than stating it as the confirmed release date.","resolved","security",[32,33,34,35],"jailbreak","iphone-duo","ios-27","calif",[37],{"name":38,"url":39},"MacRumors","https:\u002F\u002Fwww.macrumors.com\u002F2026\u002F10\u002F23\u002Fiphone-duo-jailbreak\u002F",0,{"sections":42},[43,48,52,57,62,67,72,77,82,87,92,97,102,107],{"name":44,"slug":45,"count":46,"latest_published_at":47},"AI","ai",7076,"2026-10-23T21:11:07.000Z",{"name":49,"slug":30,"count":50,"latest_published_at":51},"Security",1064,"2026-10-23T23:25:00.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Policy","policy",582,"2026-10-23T20:28:43.000Z",{"name":58,"slug":59,"count":60,"latest_published_at":61},"Deals","deals",569,"2026-10-23T14:43:38.000Z",{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",295,"2026-10-23T23:22:55.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Hardware","hardware",294,"2026-10-23T20:00:00.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":76},"Science","science",218,"2026-10-23T22:48:25.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",148,"2026-10-23T16:26:29.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Software","software",143,"2026-10-23T19:28:10.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"Dev Tools","dev-tools",122,"2026-10-21T16:00:00.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"General","general",101,"2026-10-23T18:46:30.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"Gaming","gaming",88,"2026-10-22T22:25:33.000Z",{"name":103,"slug":104,"count":105,"latest_published_at":106},"Reviews","reviews",38,"2026-10-20T12:00:00.000Z",{"name":108,"slug":109,"count":110,"latest_published_at":111},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
