Just jailbreak your iOS device with the Pangu installer. Once you’re done, you will find Pangu app on your iOS device. Tap it to open, and install Cydia. That’s it.
Pangu jailbreak is compatible with all the devices running iOS 8 through iOS 8.1. Currently Pangu tool is only available for Windows users. We have no words on the release of Mac version, but we’ll update you as it happens. Stay tuned.
