Apple introduced iCloud, a set of free new cloud services that work seamlessly with applications on your iPhone, iPad, iPod touch, Mac or PC to automatically and 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.
The free iCloud services include:
The former MobileMe services—Contacts, Calendar and Mail—all completely 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. Your inbox and mailboxes are kept up-to-date across all your iOS devices and computers.
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.
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.
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 get up to 5GB of free storage for their mail, documents and backup—which is more amazing since the storage for music, apps and books purchased from Apple, and the storage required by Photo Stream doesn’t count towards this 5GB total. Users will be able to buy even more storage, with details announced when iCloud ships this fall.
iCloud’s innovative Photo Stream service 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 a dozen photos of your friends during the afternoon baseball game, and they will be ready to share with the entire group on your iPad (or even Apple TV) when you return home. Photo Stream is built into the photo apps on all iOS devices, iPhoto on Macs, and saved to the Pictures folder on a PC.
iTunes in 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 we can match it to the over 18 million songs in the iTunes Store, it makes the matched music available in minutes (instead of weeks to upload your entire music library), and uploads only the small percentage of unmatched music. iTunes Match will be available this fall for a $24.99 annual fee.
The iCloud beta and Cloud Storage APIs are available immediately to iOS and Mac Developer Program members. iCloud will be available this fall concurrent with iOS 5.
