I want to update my iOS to iOS 16.3.3

..abideen48..

The present release is iOS 16.3.1.. A newer one might be out sooner or later.

We end-users never really know for sure, until it's a choice in iOS updates.

Automatic updates are better. Have the iDevice on charge

and set to automatic download/update; and if any newer

iOS version is compatible ~ It should download overnight.

(According to Apple's iOS Updates support page information

online, version build you ask, might be a Beta 16.x* version.

*IF that's so, you probably won't be able to use that normally.

There are several preconditions, and it's best to not get it.)

[Available updates can auto-download; yours may have iOS 16.3.1.]

Not sure but newer should be out sooner, or later!🙂
