The new build of iOS 10.1.1 arrived two days after iOS 10.2 beta 2 was seeded to developers and less than 24 hours after its accompanying public beta launched.
The new build number is 14B150. Previously iOS 10.1.1 was build 14B100.
Apple pulled a similar thing last week when it followed up on the macOS Sierra 10.12.2 beta 2 release with a minor update that showed a tiny difference in the build numbers.
We’ll update the article with new information about iOS 10.1.1 build 14B150 when and if it becomes available.
