Can I reinstall a single iOS app without losing its data? I have a single app that needs to be reinstalled. I have tried all tricks known to man in attempts to get it to work, but all have failed. There is a lot of data in this app that I'd rather not lose. It isn't explicitly iCloud-enabled, and it's not a game, so there's no hope of Game Center restoring anything. How, if possible, can I reinstall it without losing my data?
While I never tried it myself, in theory you could use something like PhoneDisk to open the app's private folder and copy all the content to your computer. Then, after deleting and reinstalling the app, you should be able to copy the content back.
