Ahead of tomorrow's release of iOS 5 and iCloud, Apple has released an update for iTunes.
iTunes 10.5 contains the following improvements:
- iTunes in the Cloud. iTunes now stores your music and TV purchases in iCloud and makes them available on your devices anywhere, any time, at no additional cost.
- Automatic Downloads. Purchase music from any device or computer and automatically download a copy to your Mac and iOS devices.
- Download Previous Purchases. Download your past music, TV, app, and book purchases again, at no additional cost. Previous purchases may be unavailable if they are no longer on the iTunes Store.
- Sync with your iPhone, iPad, or iPod touch with iOS 5.
- Wi-Fi Syncing. Automatically sync your iPhone, iPad, or iPod touch with iTunes any time they're both on the same Wi-Fi network. [Note: Apple has a knowledge base article on troubleshooting WiFi syncing.]
iTunes 10.5 brings with it compatibility with iOS 5 and iCloud, and adds support for the iTunes Match part of the iCloud service.
iTunes Match is a $24.99/year subscription service that allows users to have their entire music library synced with Apple's database of over 20 million tracks, making those songs available for use on any iCloud-enabled device. If a particular track isn't available on iTunes, don't worry, it can be uploaded so it too is available to all your devices.
If you're going to be upgrading to iOS 5 tomorrow then you will need this update, so get it now rather than having to fight it out tomorrow.
