How to reload app preferences and documents on iPhone? So I updated my iphone to new iOS and then my backup became corrupted.

I was then able to get ALL the information out of the backup unto my computer.

I now have for each app its corresponding Library and Documents.
These  contain additional folders that the apps use and the Preferences folder, which contains the .plist files.

I would like to put all this information back on my iPhone. But how?

Is there a program for this? Can this be done through iTunes?

I am quite desperate, as I would love to know how to get this done.
Once you've installed the relevant apps back on the device, open iExplorer or similar app and copy the files back on to the device in the app's data container.
