The Public Beta of iOS 9.2 has been made available to everyone by Apple, or at least those who have a compatible iPhone that is. The days of betas being solely for developers has long gone, and if you so choose you can check out build 9.2 of Apple's iOS platform, although it is worth remembering that this is not the finished and polished version that will be rolled out over the air in the coming weeks.
If you have the beta profile on your handset then you should be seeing a prompt to download the software right now. This bug fixing beta is mainly focused on improving the Safari View Controller, but we image some more features will be added between now and roll out of the finished software.
As for the stable release of iOS 9.2, Apple has not said when that will happen, but we are willing to stake that it will happen sometime during November.
