Any idea when iOS 9 beta 2 comes out... And if it will contain a new music app...or fix the problem with email crashes as well as 3rd party apps?
iOS 9 beta 2
You mean beta 3. Eddy Cue tweeted on Tuesday (6/30) saying "early next week," and typical beta release schedules are on a Tuesday at 10 AM PDT / 1 PM EST. It will definitely contain the music app, bringing along Apple Music. As for crash fixes, who knows. It's a beta.
