It looks like we are getting close to the release of iOS 9.2 for the iPhone and iPad as Apple has released the fourth beta of the OS to developers and members of its public beta testing program.
The new iOS 9.2 beta 4 comes with support for third party action extensions for Safari and also support for AT&T’s NumberSync feature.
The software comes with the build number 13C5075 and it is available to download to registered developers and registered members of Apple’s Public Beta testing program. The update comes just eight days after the release of beta 3 of 9.2.
The software is available as an over the air update for registered devices and also from Apple’s developer portal. If you are running the latest beta you can now enable NumberSync if you are using AT&T’s network.
In order to do this you need to go to Settings > Phone > WiFi Calling and then add WiFi Calling from other devices.
As this is the fourth beta of the software we cannot be that far away from the release of iOS 9.2 to everyone, as soon as we get some more details on when the update will be made available for the iPhone, iPad and iPod Touch, we will let you guys know.
