Why can’t I get 17.02 update but I have 17.1

If you're on iOS 17.1 at the time of writing, that means you have Beta Updates enabled in Settings > General > Software Update.

To remove yourself from the beta update channel, set Beta Updates to "Off".

The current version is 17.0.2, not 17.2.

Do you have 17.0.1 or 17.1? If you have 17.1, you have enrolled your phone in the beta program. 17.1. has not been released to the public yet.

If you have iOS 17.1, you have a beta version that is newer than 17.0.2.

Please clarify exactly which version you have.
