What is iTunes? Do I need it?
iTunes is a program made by Apple for Mac and Windows. It is a program for managing your iDevice's content, backups, and upgrades. As of iOS 5, iTunes is no longer required, except for putting music on your device and performing full, encrypted backups. You can activate, upgrade, and back up your iDevice using iCloud as of iOS5. If you are on Windows and still want iTunes, you can download it from Apple.com.
