Have y'all updated to iOS 9.1 beta 1? So far I hear it's better than the iOS 9 beta or GM build and excellent battery life. I just installed and so far so good. I'll see tomorrow though when I get a full days worth of usage tomorrow. Oh and I noticed the carrier profile is 21.5 and the prl is 55029. I believe it used to be 55028?? Oh and there's some new emojis.
