14 DAY TRIAL // After the big announcements of the OS X 10.11 El Capitan Beta 1 and iOS 9.0 Beta 1 operating systems, Apple has released earlier today, June 9, the fourth Beta of the upcoming iOS 8.4 mobile operating system for iPhone, iPad, and iPod touch devices.
According to the internal release notes, which are available only for developers, iOS 8.4 Beta 4 Build 12H4125a is here to fix an issue with Siri as it could not be used to control iTunes Radio in the previous Beta of the operating system.
As you might know, iOS 8.4 will introduce a redesigned Music app that has been mediatized in the last couple of months and demoed by Apple during its keynote speech at the WWDC 2015 event.
Apple has also unveiled its brand-new Apple Music service to go with the revamped Music app in iOS 8.4. As such, it has been announced that the final release of iOS 8.4 will arrive at the end of the month, on June 30, 2015, with Apple Music support.
