The iTunes application on the iPhone is a small version of the iTunes store found in the Mac and Windows iTunes application. You can see the featured and new releases, top ten lists, browse by genre and search. You can then purchase music and get it directly on your iPhone.

The search functionality allows you to search for group, album or song name.

When you select an album, you can purchase the entire thing, or a single song. You can also preview a song by clicking on its listing. It plays a 30-second clip.

Click on the Downloads button at the bottom of the screen to see any songs you have purchased. These will automatically be added to your iPod Application as well, so after purchasing there is no need to use the iTunes Application to play the songs.

You can currently only purchase music on the iPhone. The full iTunes application on Mac and Windows allows you to purchase music videos, TV shows and movies as well.
