If you have a large digital music collection, you can make your own custom toques para celular to use on your phone by using an audio editor or an audio splitter like WavePad or Mc3splt. Or, you can use iTunes to create ringtones from your existing iTunes music library.

You can then save these new ringtones to your computer, transfer them to your iPhone or Android, and use them as a unique ringtone on your phone. Some ringtones are even compatible with Apple's iMessage service.
