Previous versions use similar menus and procedures. How to Reset the Settings on Your iPhone After you back up your iPhone and decide what you want to erase, choose the correct reset option from the Reset page of the Settings app. Always back up your iPhone before deleting settings or restoring it back to its factory default state. If something goes wrong, you can restore the data without permanently losing anything. Open Settings > General > Reset. Tap the option that corresponds to what you want to reset on your iPhone. If any prompts are shown, follow the on-screen steps to complete them and finalize the reset. Because the Reset All Content and Settings option resets the entire phone, you'll have to set it up again from scratch if you plan on using it after the reset.
