You can create ringtones (the sound your iPhone makes when someone calls you) from many songs purchased from the iTunes Store. You pay a fee for each custom ringtone.
Eligible songs have a bell icon next to them:
If you don’t see the bell column in your iTunes library, choose ViewÂ > View Options, and then select Ringtone. (If a message appears, click Check Songs.) If you don’t see the bell column in the iTunes Store, follow the same steps while you’re in the iTunes Store.
To create a ringtone:
Choose EditÂ > Preferences, click General, and then make sure Ringtones is selected.
Make sure you’re connected to the Internet.
Select the song you want to use, and then choose StoreÂ > Create Ringtone.
In the editing window that appears, choose the part of the song you want to use as the ringtone.
You can use up to 30 seconds of the song.
When you’re ready, click Buy.
Important:After you click Buy, you can change the ringtone’s name and other information, but you can’t select a different portion of the song.
You can sync ringtones created with iTunes with any iPhone you own, and play them on up to five authorized computers. After you sync your iPhone, you can assign the ringtone to one or more contacts.
Note:iTunes ringtones are available only in some countries, and can be used only on iPhone.
