iOS 17 is here, and so is the first developer beta build for iPhones. Since it is developers beta, it is only available to developers, and if you are interested in trying out the new features or need to work compatibility for your app before the stable version drops for everyone, here's how you can install iOS 17 developer beta on your iPhone.
Early betas are known to have a number of bugs and problems, and the developer beta is only for development purposes. So, it is not recommended to install iOS 17 on your primary iPhone. Instead, if you have an older iPhone that is not being used, it would be safer to install it on that device.
If you do not want much hassle, it would be best to wait until July till the public beta comes out, or you can also wait till September, when the stable version rolls out for everyone.
Before proceeding with the installation, do take a full backup of your iPhone. Since rolling back to the stable version will wipe out all the data.
