iOS 8.3 Beta 4 Released to Developers & Public Beta Users for Testing
Apple has released the fourth beta release of iOS 8.3 to those registered with the iOS developer program, or who are participating in the iOS Public Beta. The build is versioned as 12F5061 and is available now for compatible iPhone, iPad, and iPod touch devices.
The simplest way to install iOS 8.3 beta 4 is through the Over-the-Air software update mechanism on the iOS device. This is accessible through Settings > General > Software Update. As always, back up the device before updating system software, this is particularly important when that iOS software is a beta version. Additionally, it is not advised to run beta software on a primary device.
The new beta build IPSW can also be downloaded from the iOS Dev Center for those registered with Apple.
iOS 8.3 continues to focus on improvements, bug fixes, and feature enhancements, and the version is expected to include new diverse Emoji icons, wireless CarPlay connectivity, Apple Pay improvements, new languages for Siri, and Google 2-factor authentication support.
While this is the fourth beta of iOS 8.3 overall, this is the second release available to Public Beta users of iOS. There is no known timeline for iOS 8.3 being released to the general public, but one could reasonably expect a final version to arrive before Apple Watch debuts.
Separately, Apple has also made Xcode 6.3 beta 4 available to iOS developers.
