If you are among the thousands of people trying to score an iPhone on launch day, you'll need to get Apple's iTunes latest version 7.3 for compatibility with your new phone. The update is available through the Software Update system preference or you can also head to our Downloads section to grab your Windows or Mac version of the program.
The new version will enable iPhone users to activate service for their phone and sync the iPhone with music, movies, TV shows and more. Other features include the ability to share digital photos from any computer in a home network with an Apple TV.
