Apple has just released iTunes 10.5 via Software Update (some may not see it yet), in preparation for the release of iOS 5 and iCloud tomorrow. The specific release time (either morning or afternoon) is unknown, but just keep your eyes and ears peeled here.

You can also download it directly from Apple’s website.

iTunes 10.5 brings:

• Automatic downloads of apps to all your iOS devices
• iTunes Match (US only at the moment)
• Purchase history
• iTunes in the Cloud
• WiFi syncing

iOS 5 will be available tomorrow, just a couple days before the launch of the iPhone 4S. Some pre-orders from Apple have already arrived around the world.
