I want to go back to a older version of a recently updated app. I should have a older version of the app saved in iTunes. Don't want to do a full wipe and restore, just want to restore a single app. I would delete the current app on the iPad. Then connect to iTunes, but the sync process is always a mystery, never sure what it will do. Can I use iTunes and just copy over that one app? Do I need to set some settings in iTunes before connecting so it does not change any thing else on the iPad?
