Apple's iOS 8.2 firmware which brings support for WatchKit may not be released until March, according to BGR.
We’ve been told by a trusted source that Apple isn’t planning to release iOS 8.2 until March, according to the most recent roadmap. While iOS 8.2 will bring some general improvements and fixes to the company’s mobile operating system, the big news is the support for Apple Watch.
Considering Apple has already released a fifth beta of iOS 8.2, March seems a bit far off. However, Apple CEO Tim Cook recently revealed that the Apple Watch won't ship until April.
