Apple has seeded the third iOS 8.2 beta to developers this morning. The release comes a week after the second iOS 8.2 beta, and follows last week's public launch of iOS 8.1.2, which brought about a fix for disappearing ringtones.
The new 8.2 beta can be downloaded either over-the-air, or via Apple’s developer portal, by all registered iOS developers. It’s unknown what new features the firmware will bring, but it will enable support for Apple's WatchKit.
