If you are Apple, it's only logical for you to take a very good care of your iTunes business. After all, this particular online music retailer is the third biggest in the U.S. today. Just before the month of May ended, Apple released iTunes 7.2. This time, prior to the launch of the much-awaited iPhone, the Cupertino-based company decided to roll out build 7.3.

Needless to say, this update is connected to the Apple's new mobile phone. Here is the complete changelog for iTunes 7.3 as provided by Apple itself:

• Activate your iPhone service
• Sync iPhone with your music, movies, TV shows, and more
• Wirelessly share digital photos from any computer in your home with Apple TV

There are two versions of iTunes 7.3 - one for Mac users that is around 33.8MB in side, and another for Windows-based consumers (47.4MB). If you want to activate the iPhone service, please take note that you should be running at least Mac OS 10.4.10 or Windows 2000 with Service Pack 4.
