Apple just released iOS 9.0 Beta 4

Apple has just released iOS 9.0 Beta 4 build 13A4305g, for those enrolled in the Apple Developer Program.

The fourth Beta of the upcoming iOS 9 for iPhone, iPad, iPod devices is available for download, in IPSW images for select devices directly from the Member Center of your Apple Developer account.

Users who are not enrolled in the Apple Developer Program will be able to update their devices in the coming days, when Apple makes the update available via OTA (Over the Air) updater.

However, before installing the public beta, you should be aware that it is a pre-release of the upcoming iOS 9 and is not designed for the devices you are using.

So if you care about the stability of your device, it would be best to avoid installing it.
