What You'll Get If You Install iOS 9.2 Beta
If you do decide to install iOS 9.2 beta 1, know that you'll gain access to some new features and enhancements.
The iOS 9.2 update delivers some new features including improved Safari extensions, improvements to the Music app, fixes for the App Switcher, improvements to multitasking on iPhone 4s, improvements to 3D Touch on iPhone 6s Plus, and more.
It's not as exciting as iOS 9.1 but we do expect Apple to introduce more functionality as the iOS 9.2 beta progresses. If those features don't sound exciting to you, skip the first beta and wait for the iOS 9.2 beta 2 to roll out.
