In this one I go over some Privacy, Security, Battery Saving, and Data Saving settings you can use on your iPhone until you can move over to a more secure option like the Librem 5 USA from Purism. iOS 15 does add several security features including some Facebook was not happy about so that is a good thing if they work the way they are supposed to work that is.
