It is not possible to "go back". Apple has never supported downgrading the iOS version.


The apps that are not working likely need to be updated by at the app developers. Contact the developers at each app to see if they have updated their app for the latest version of software.


They might tell you to delete the app and then download and install it again from the App Store.
