Apple started implementation of IOS 9.2.1 update for all iPhone, iPod and iPad devices. Kick-started after the beta version of IOS 9.2.1, which appeared in eager testers last month. At the same time, IOS 9.3 beta was released only for those who are part of the beta testing program from Apple.
As you might guess from the version number, IOS 9.2.1 portends a serious revolution. It does not come with new features, but to concentrate on improvements in productivity and reliability.
Included is a solution to the problem with the installation of applications when working with MDM server. For now it is unclear whether the open bug in the battery indicator will also be removed in iOS 9.2.1. But surely there are some improvements that we do not know yet.Source: GSMARENA
