A group of Chinese developers known as “TaiG” has released a jailbreak for iOS 8.3. The jailbreak is untethered, meaning it can boot and reboot freely without the assistance of a computer, and installs on any iPhone, iPod touch, or iPad which is running iOS 8.3.
Jailbreaking is generally not recommended, instead it’s best reserved for advanced users who understand what a jailbreak entails, and why it may be desirable (or not) for some iPhone, iPad, and iPod touch devices. Essentially, jailbreaking iOS is a means of modifying iOS system software so that it can run third party and unauthorized code, which can includes various applications, system tweaks and themes, modifications. We suggest only very advanced users with a compelling reason consider jailbreaking their hardware, as there are many reasons not to jailbreak a device, including that Apple may deny warranty service to an iPhone or iPad that has modified iOS software from the jailbreak. Always jailbreak at your own risk, it is not for casual users.
Nonetheless, users who are knowledgeable and understand the risks associated with jailbreaking can download the TaiG untethered jailbreak tool for iOS 8.3 now from the groups website here.
Currently, the TaiG jailbreak for iOS 8.3 only runs on Windows, so Mac users will need to either turn to running Windows in a Virtual Machine, a PC, or Boot Camp if they really want to jailbreak their iPhone or iPad. Beyond that, you’ll need to back up the iOS device and use a USB cable to install the jailbreak. Directions to install the jailbreak are included on the TaiG site and should look familiar enough to those who have jailbroken a device before.
It’s unclear when an OS X version of the TaiG Jailbreak for iOS 8.3 will be released.
