To the person who said you can't set MP3 ringtones, you can.
If youre a Mac user (you need to be to use this feature) you can simply open GarageBand, create your own ringtone (up to 40 seconds) and import to your iPhone.
If you want a song, simply load it (such as from iTunes) and cut the song until you get the part you want as your ringtone.
It's easy and it's free.
