The Taig Jailbreak is out for iOS 8.3 As of right now, many tweaks from Cydia will not yet work but we hope this is solved later today. As of this moment I suggest holding off on the jailbreak until things are more stable.Things are pretty stable now so this is probably a good time to get updated and onto iOS8.3 if you ever feel the need to do so in case Apple puts out an update and closes the jailbreak holes. You can read about the new jailbreak here.
Likewise, if you plan to stay on 8.1 or 8.1.2, that’s probably ok also.
