Thanks to the appshopper.com RSS feeds, I've downloaded a lot of free apps: some good, many forgettable. Is there a simple way to see a list of uninstalled iPhone apps so I can re-evaluate and delete a lot of the duds?
I've seen programs that scan my iTunes library for apps (though some of them miss a lot of results), and IIRC it's possible to read an iTunes-managed iPhone backup to see which apps are installed there.
So, are there any existing utilities that do this? Failing that, I'll upvote/accept an answer that points me in the right direction to create such a utility myself.
