Without deleting the app itself, can I delete an app's related data?

In iTunes you can select which apps to sync with your phone. Uncheck the one that you want to delete and sync with your phone. That will delete the app from the phone only (iTunes will still have a copy) and it also will delete the app's datafiles from the phone.

Then you can recheck the box in iTunes, sync again, and the app will be reinstalled on the phone.

No, deleting the app and then re-downloading it is the method to clear out all settings. Some apps will have an option on their settings page to clear out data or caches, but not many.

So, re-downloading it from my iTunes library? – Chris Dwyer Dec 17 '09 at 17:58
You will have to delete it on the phone and in iTunes and then download it again, or you can delete it on the phone and download it again directly on the phone. – ridogi Dec 17 '09 at 18:17
