Fantastic!

Worth every penny. You can use any ripped mp3 (cannot use DRM protected purchased songs - Apple seems to want to charge you twice and make you buy the same jingle as a ringtone) and cut out up to a 40 second .m4r file which you email to yourself and import using iTunes onto your iPhone. Very simple and easy to use.
