The best part in SetBack tweak is that it allows you to save every part of any particular iPhone setup you might have, including all tweak preferences, wallpapers, icon layout and Winterboard theme applied. To save a setup, simply tap on the SetBack icon from the Home screen and tap on the plus button at the bottom of the user interface. Each setup is stored as a thumbnail that looks like the iOS multitasking menu.
Once you hold your fingers on any of the existing setups that you have already saved provides some additional options, including update, rename and delete. These controls are self explanatory based on their names, providing SetBack with multipurpose functionality and making it a truly flexible tweak. To revert a saved setup, just tap on the setup and confirm to begin the reverting process. Your device will then proceed to begin loading the old setup that you saved, with an automatic respring at the end to load the setup.
It is really a very useful tweak for users who download many themes/tweaks on their devices..
