iOS 11.1 Public Beta 1 was released for iPhone and iPad by Apple, this version of the operating system coming just a day after iOS beta 11.1 1 has been released to developers. iOS 11.1 Public Beta 1 is basically iOS 11.1 beta 1, but in the version available for regular users, both offering exactly the same things, so if you have one, there's no point in installing the other.
iOS 11.1 Public Beta 1 is offered quite quickly by the Apple company, I would have expected the update to be available for iPhone and iPad only after iOS 11.1 beta 2 is released. However, considering that iOS 11.1 beta 1 does not bring many important news, Apple probably considers that iOS 11.1 Public Beta 1 has no way to affect users' phones very much, so it offers the update.
iOS 11.1 Public Beta 1 can only be installed if you have a beta testing profile installed on your phones, which can be obtained from the beta.apple.com website. This profile will allow you to install future public beta versions released by Apple, so you can use it whenever you need to test any new versions of iOS that the American company will release for us.
