Everything you need to know about setting up, backing up, restoring, and updating your iPhone, iPod touch, and iPad, and managing your iTunes apps, books, music, TV shows, movies, Match, and Photo Stream in the cloud
iCloud is Apple's online service designed to make managing your iPhone, iPod touch, iPad, and Apple TV, and your iTunes content easier and more automatic than ever. Like the name implies, iCloud is based in the "cloud", which is a trendy way of saying giant data centers filled with servers that you can access from your device over Wi-Fi or 3G/4G internet, wherever you are, whenever you want. It consists of several services that work with the apps on your iPhone, iPod touch, and iPad, and with iTunes and a handful of desktop apps on Mac and Windows. Most iCloud services are completely free, although additional storage and services are available for purchase.
