Use google you can find others that work.
Did you double-click the file to play it? When you do, it should load and play through iTunes, and then it can be synced to your phone.
In any case, Google "Audiko" and you'll find an awesome site where you can upload/make/download your own ringtones. Put "Crank" in the search bar, and you can download a ready-made crank ringtone in the proper format...
