But, now that doesn't matter. I was opening this thread to post that TaiG has released an updated version of their tool - and it jailbreaks iOS 8.1.2.
So, I recommend you go ahead and upgrade to iOS 8.1.2 and jailbreak that.
Just used the new version on an iPhone 6 upgraded to 8.1.2 and it worked flawlessly. Two thumbs up.
