Apple iOS 9 Public Beta 3 Release Information

Apple launched Public Beta Program for iOS 9, OS X 10.11 and watchOS 2 as per schedule in early July this year to let everyone join in the fun of beta testing Apple’s upcoming operating systems without having to pay any subscription fee for Apple’s Developer portal.

If you’re already running any previous version of iOS 9 Public Beta, you can update to the latest Public Beta 3 using OTA (Over-The-Air) update system by heading to Settings > General > Software Update.

Additionally, you can help Apple deliver a more quality iOS release by filing reports for bugs in public beta builds you’re testing. If you don’t know how to do this, you can follow the instructions on it here: How To Report iOS 9 Beta Bugs To Apple [Guide].
