Just a heads up for anyone who's hesitated (I am not an early adopter and I've been jail breaking since I first did it in my 1st gen touch)... I just updated and JB'ed my iPad air (from 7.1.2 JB) and everything that I had (iFile, movie box, cc settings, etc.) is working fine. No issues with safari or anything else. Also just JB'ed my iPhone 6 and all Stock functions (touch ID, Safari, etc.) are working great! I simply DFU'ed both devices to 8.1 on my Mac, then went over to my windows PC and Pangu'ed. No issues here to report. I only made sure to turn on airplane mode. I set up both as new decides and reinstalled my apps and email accounts.
