As you might have heard, Apple has announced iTunes in the Cloud, allowing users to download past iTunes Store music and music video purchases directly to their iPhones, iPads, or iPod touches, free of charge. If your device is running iOS 4.3.3, simply open the iTunes Store app and look at the bottom row of tabs. You should see a new tab called Purchased, from which you can access and download all your past iTunes Store music purchases. You can look for specific songs by searching, browse past purchases via Recent Purchases or Not On This iPhone automatically-populated lists, or browse by artist. When you’ve found the song or album you were looking for, simply tap the cloud download button to the right of the listing. Just remember that if you’re on 3G, these downloads will count against your data limit, so try to stay away from grabbing up album after album until you’re back on Wi-Fi.
