I know this question might have been asked before, but since there is a new JB today for 4.3, I want to make sure I've got it all right so I don't lose my settings/JB apps. My iPhone 4 is currently Jailbroken and running on 4.1. I want to keep settings/themes/all apps and JB apps as well. What are the steps to makes sure I keep all of it? Thanks.
