It's possible to update to the latest developer version of the iOS 9 beta directly from the iOS 9 public beta. If you want the latest and greatest updates offered by iOS 9 beta 4, but you're currently running the public beta, listen up—it's super-easy to upgrade to the latest developer version of the iOS 9 beta.
iOS 9 beta 4
I think this can definitely warrant a finally. Apple has disabled the ability for users to leave app reviews in the App Store while running iOS betas.
The change seems to be retroactive, as I tested it from both the just-released iOS 9 beta 4 and the previous beta 3, and both throw up errors that the review feature isn't available while running a prerelease version of iOS.
I've been playing with iOS 9 beta 4 on my iPod touch, iPhone and iPad for the last few hours, and I'd like to share my thoughts on the beta release.
First and foremost, this is the first beta firmware to work on the iPod touch 6th generation, and as expected, it runs like a champ. The iOS 9 beta on the old iPod touch 5th generation was barely usable due to the device's lack of power, but this new iPod touch handles things with no issues.
Another big feature is the return of Home Sharing. As promised by Apple executive Eddy Cue, Home Sharing is now back where it belongs in the Music section of the Settings app.
I've created a video walkthrough to showcase many of the new features found in iOS 9 beta 4. Have a look and let me know what you think about this latest beta release.
Following the release of iOS 9 beta 3 for the iPhone, iPod touch and iPad two weeks ago which gave developers access to Apple Music on their development devices while bringing out the News app and a host of refinements, Apple today released iOS 9 beta 4 (build 13A4305g) to registered members of the Apple Developer Program.
