Download New Version of iTunes 9.0.2
Apple has updated iTunes to a new version, 9.0.2, with a few other interesting developments, such as compatibility with Apple TV 3.0
As I always say, I advise waiting just in case update, Apple has not introduced any new security system that will bring headaches.
I advise patience, at least until the DevTeam or Geohot says it is safe.
New developments are bringing among other things, compatibility and menus deAppleTV 3.0, iTunes Extras, LP iTunes Genius Mixes, Internet radio, iPhoto Events, and iPhoto Faces, and correction of various bug and improved accessibility.
To update if you want, when you open iTunes is available.
