Apple iCloud features unveiled

Apple today unveiled its iCloud service, which will be available today to developers.

The new set of free new cloud services will wirelessly store your content in iCloud and automatically and wirelessly push it to all your devices. When anything changes on one of your devices, all of your devices are wirelessly updated almost instantly.

T3 runs through the key features of the iCloud:

All MobileME Services:

Contacts, Calendar and Mail have all been re-architected and rewritten to work seamlessly with iCloud. Users can share calendars with friends and family, and the ad-free push Mail account is hosted at me.com. Inbox and mailboxes are kept up-to-date across all your iOS devices and computers.

Backed up App and iBookstore:

The App Store and iBookstore now download purchased iOS apps and books to all your devices, not just the device they were purchased on. In addition, the App Store and iBookstore now let you see your purchase history, and simply tapping the iCloud icon will download any apps and books to any iOS device (up to 10 devices) at no additional cost.

Automatic backup:

iCloud Backup automatically and securely backs up your iOS devices to iCloud daily over Wi-Fi when you charge your iPhone, iPad or iPod touch. Backed up content includes purchased music, apps and books, Camera Roll (photos and videos), device settings and app data. If you replace your iOS device, just enter your Apple ID and password during setup and iCloud restores your new device.

Document Changes:
iCloud Storage seamlessly stores all documents created using iCloud Storage APIs, and automatically pushes them to all your devices. When you change a document on any device, iCloud automatically pushes the changes to all your devices. Apple’s Pages, Numbers and Keynote apps already take advantage of iCloud Storage. Users will be able to buy more storage over the free 5GB it comes with, details will be announced when iCloud ships in Autumn.

Photo Stream:

Photo Stream automatically uploads the photos you take or import on any of your devices and wirelessly pushes them to all your devices and computers. So you can use your iPhone to take photos and they will be ready to share on your iPad. The last 1,000 photos are stored on each device so they can be viewed or moved to an album to save forever.

iTunes:
The Cloud lets you download your previously purchased iTunes music to all your iOS devices at no additional cost, and new music purchases can be downloaded automatically to all your devices. In addition, music not purchased from iTunes can gain the same benefits by using iTunes Match, a service that replaces your music with a 256 kbps AAC DRM-free version if Apple can match it to the over 18 million songs in the iTunes Store.

iCloud will be available this autumn, coinciding with the release of iOS 5. Users can sign up for iCloud for free on an iPhone, iPad or iPod touch running iOS 5 or a Mac running Mac OS X Lion with a valid Apple ID.
