iOS 8.2.1 is the future version of the iOS operating system that the Apple company is preparing to bring to the market at the moment, it is going to bring us at least one important novelty, it is related to the Apple Watch and is represented by the Activity application that you can access even now in iOS 8.2 with a little trick. The Apple company has not officially announced the release of iOS 8.2.1 for its terminals, but the Activity application is hidden in iOS 8.2, so an update of the operating system will be necessary to make it visible in our terminals and to be able to use it together with the Apple Watch.
For now there are no details about iOS 8.2.1 news which could be made available to us by those from Apple together with this new version of the operating system for its terminals, but I assume that we will also see some bug fixes and possible improvements to the general performance. Apple released iOS 8.2 especially for the Apple Watch, solving a multitude of problems in the subsidiary, with the implementation of some not-so-notable novelties, so the appearance of iOS 8.2.1 is required by offering the Activity application and the functionality that is the basis of the Apple Watch.
Considering that Apple has already announced the launch of the Apple Watch on April 24, with pre-orders from April 10, it is quite clear that iOS 8.2.1 will be released between April 20 and April 23, so in the days preceding the appearance of the future smart watch the Apple company. To be completely honest, I wouldn't expect iOS 8.2.1 to bring any major changes apart from the Activity app and possible fixes for Apple Watch-related features, so you don't have to wait for who knows what major changes that Apple could make.
