A week after the iOS 8.2 beta 2, Apple released the third, which seems to be no different from the previous one. Firmware continue to improve for the start of sales of Apple Watch, which is scheduled for spring.
At the moment we know only that the build number izmenilcya firmware 12D5452a on 12D445d. Clearly something in the updated application development environment for iOS and OS X Xcode 6.2 beta 3 c support WatchKit. New firmware can be downloaded as OTA-update, who sat on the iOS 8.2 beta 2, or through a portal for Apple developers.
It is still unclear when will the official iOS 8.2. Someone suggests that it will not until the start of sales Apple Watch, which is scheduled for early next year. There is even an opinion that this will come to an intermediate version of iOS 8.1.3 to fix minor bugs. Others assert that the release is not far off.
