The update, build number 13A4325c, is available as an over-the-air update and can also be downloaded through the Apple Developer Center.
Today's beta introduces new wallpapers and heralds the imminent release of a WiFi calling option for AT&T users. For a full list of changes in the beta, make sure to check out our iOS 9 Beta 5 Tidbits post.
iOS 9 beta 4 brought the return of Home Sharing for music and it fixed a bug that had prevented the iPhone's volume buttons from being used as a camera shutter. It also introduced a new look for Handoff in the app switching interface.
In addition to providing developers with five betas, Apple has also seeded two iOS 9 betas to public beta testers. The company plans to release iOS 9 to the public in the fall, likely alongside new iPhones.
