One of the existing ways to detect a new version of iOS without having to be in the beta period is to use the website traffic statistics. This is something that MacRumors has been monitoring for several years since they usually detect new releases by browsing their portal and, weeks later, they are officially launched. This is what happened a few months ago with iOS 17.2.1 or iOS 17.0.3.
