It's been less than an hour since Apple's announcements and the first iOS 9.1 beta is now available for download to all developers, just like the company promised during the event.

If you are an iOS developer, then you should keep in mind that this is a pre-release version for iPhone, iPad, and iPod touch.

It's also worth mentioning that once you upgrade to iOS 9.1, you won't be able to restore your device to an earlier version of iOS.

In order to be able to download iOS 9.1 beta, you will need to sign in with the Apple ID associated with your Apple Developer Program or Apple Developer Enterprise Program. If you're not a member, then you won't be able to download it.

The good news is Apple fans who are not developers won't have to wait too long for iOS 9 to arrive on their iPads and iPhones.
