I had no problems jail breaking mine, I use this tweak to show off the touch ID. Love it
I think Siri will still open the app even though you have it "TouchIDed".
just tried it, NOPE! Still secure, i activated Siri and said, "Open messages", soon as i said that it showed, "Fingerprint Scanner required to open messages", then Siri came on and said "I couldnt open messages, my apologies". I then put my finger on, and it opened right up. Perfect. Ill make another video if you want to see.
