If you're upgrading, replacing, or restoring your iPhone, iPod touch, or iPad, using iCloud can get you back up and running in no time. Unlike restoring from iTunes, you don't need to plug right into the specific Mac or Windows PC that holds your iTunes library. All you need is a Wi-Fi connection and some time. We've even done it right at the Apple store, right after swapping out our iPhones and iPads. It's simple once you know how.
