Apple has stopped signing iOS 8.1.2 meaning that it is no longer possible to restore to the firmware version to jailbreak your iPhone, iPad, or iPod touch.
Unfortunately, Apple blocked the exploits used to jailbreak with the release of the current iOS 8.1.3 firmware.
If you are on iOS 8.1.2 take extra care not to accidentally update your device.
If you haven't jailbroken yet, you can still use TaiG or PP to jailbreak.
