You Can Jailbreak iOS 8.1.2 with TaiG
Users who are interested in jailbreaking their iPhones and iPads will find that iOS 8.1.2 can be jailbroken using an updated version of the TaIG tool. The new version of TaiG came almost immediately after the release of iOS 8.1.2, which apparently does not patch the method utilized by the jailbreaking utility.
