Last week, Apple pushed out iOS 9 beta 3 to developers and iOS 9 Public Beta 1 to us regular testers. Just because Apple is placing so much focus on iOS 9 doesn’t mean that its done with iOS 8, though.
Apple today pushed out an iOS 8.4.1 beta update. The update is build 12H304, and it can be downloaded from Apple’s Developer Center and then installed on your iPhone, iPad, or iPod touch.
As for what’s included with the iOS 8.4.1 beta, that much is unknown right now since the update was just released. Considering that it’s an x.x.1 update from iOS 8.4, though, it’s likely a bug fixing update that’s mean to offer a smoother user experience.
