Talk about quick off the mark! iOS 7.1.2 may have only just been released, but the Pangu jailbreak (which offers an untethered solution for iOS 7.1.x-powered Apple devices) is already compatible with the latest version of Apple’s mobile operating system.
This means that it is safe for jailbreakers to update to the latest version of iOS, before re-jailbreaking their iPhone, iPad, or iPod touch with the same Pangu method.
Released yesterday, iOS 7.1.2 adds improvements to the iOS Mail application and iBeacon. Pangu launched towards the end of June — initially only for Windows users, but arriving on the Mac not long after. Users can download iOS 7.1.2 over-the-air (OTA) from Apple, while Pangu can be downloaded free of charge from the link below.
