Apple issues first developer beta of iOS 9.2.1
The new beta release is identified as build 13D11. Apple has warned developers that devices updated to iOS 9.2.1 cannot be restored to earlier versions of iOS.
Registered developers can access the update through Apple’s developer center website, or via the Software Update option in an iOS device’s Settings application.
The identifier of 9.2.1 indicates that the forthcoming update is likely a minor update with bug fixes and security updates. Apple typically saves new features and major changes for a point-one release.
