What doesn't iTunes backup? An app of mine is having issues with certain communications, and backup/restore resolves issue. Deleting and re-downloading the app doesn't resolve. This isn't acceptable solution, so I want to know what isn't backed up to figure out what is going on.
iOS 5.1
An interesting scenario. I thought deleting the app deleted everything, not only the app filesystem but NSUserDefaults, associated keychain items, etc. Does it matter whether you delete the app in iTunes or on the device?
Rather than ask what iTunes doesn't backup, start with what is does backup. See iTunes will back up the following information on this page for an extensive list.

Also read this if you use iCloud.
I wonder if session info persists if you delete an app. I'd reviewed the list, and what surprised me is that it said cookies were restored... maybe that only applies to safari set cookies.
Never thought about deleting the app in iTunes...
