iCloud, iOS 5, iTunes 10.5, and OS X 10.7.2 Released

type="html">

In accordance with last week's keynote, Apple users have some downloading to do: iOS 5, iTunes 10.5, and Mac OS X 10.7.2 have all been released. These updates collectively enable Apple's new iCloud service, which will eventually replace the older MobileMe service and provide syncing and backups for users' documents, pictures, and other data.

iOS 5, which supports the iPhone 3GS, 4, and 4S, all iPads, the third and fourth-gen iPod Touches, and the Apple TV 2, enables a number of other new features: a new notifications system and the Notifications Center, the iMessage protocol, wi-fi syncing, and over-the-air OS updates. You can download the update to your devices after downloading iTunes 10.5. Expect our full, in-depth review of the new OS soon.

Mac OS X 10.7.2 doesn't bring major new features to the OS, but it does apply a range of security and reliability patches to the operating system which should help with some of the teething issues most new OS X releases have. Release notes for the update haven't yet been published, but we'll update the article to link to them when they're live.

Along with these updates, Apple has also published a Lion Recovery update, which updates Lion users' recovery partitions to work better with the new Find My Mac feature.
