Apple has released iTunes 10.5, and while it may seem like an ordinary update, the big news is the introduction of iTunes in the Cloud, which automatically downloads your previous purchases across virtually any of your devices.
This is a potential game changer for Apple’s cloud-based service, as it now allows you to access your music library anywhere, providing that the device you’re using has iTunes installed. You can also choose between having Apple update your library automatically, or you can go through it song-by-song if you want. Additional features include WiFi syncing across iOS devices, and a new feature called iTunes Match, which isn’t quite ready yet but should be available soon.
If you already have iTunes, simply go to Apple Software Update and it will take care of the rest. If this is your first time, head on over to the iTunes page.
