Deleting all apps, but not settings
I would like to delete all of the apps off of my kids' iPad, but keep the settings. As a consequence of some bad choices, they've lost the use of the device for a month except for a couple of education apps. Since the device has over 200 apps installed, I am trying to figure out if there is a relatively easy way to delete all of the apps (I can reload the education ones), but keep all of the settings that I have for the device. I've backed up the iPad and figured I could restore all the apps once their month of purgatory is over. Any thoughts or suggestions on how to do this quickly?
