Today, Apple officially released the first beta of iOS 9.3.3 build 13G12 to developers, according to the update log, “This beta version of iOS 9.3.3 contains bug fixes and improvements.” Now the registered developers can download iOS 9.3.3 beta 1 via an over-the-air update, or directly download the firmware ipsw file from Dev Center.
The beta firmware is available for devices registered to test pre-release versions of iOS and will take up 1.4GB of your iPhone’s hard drive space.
As a minor 9.x.x update, this beta may mainly address bricking issues with the 9.7-inch iPad Pro, which many owners were affected by when the 9.3.2 firmware was released.
The bug caused devices to get stuck in a cycle of endless ‘Error 56‘ reboots and resulted in Apple pulling the update from the App Store for owners of the smaller iPad Pro.
So iOS 9.3.3 beta 1 may also end up fixing the error 56 issue. Apple has scheduled WWDC 2016, starting from June 13th where we can expect the big announcement of iOS 10 from Apple. As the mega event is just a couple of weeks away, we cannot expect the company to release the public version of the iOS 9.3.3 as of now. We will update the post once we have any official confirmation.
