    I do this with iTunes.

    First, in the iTunes preferences make sure that your importing preferences are set to MP3 with an appropriate bitrate for your phone.

    Then right click on the song, click get info, and select options. Set the stop time to what you want. Finally right click on the song again and click convert to MP3.

    That'll generate a new MP3 of the song that's the length you wanted. You can then change the end time back for the original song, transfer the new one, and then delete it from iTunes.

    That's probably a little more complicated then garage band, but I don't have it installed, and this was the simplest way without downloading anything.

    actually, your method works great, but it wont let me convert the file to mp3. the song is in mp4 format and it wont let me convert. is there a way to do this in itunes?

    you could also take a pair or scissors...

    Quicktime works great too, but you might need the non pro edition. I do so i dont know.

    If it actually is a song, then you can rename the mp4 file to m4a and iTunes will see it.

    Keep in mind that for iTunes to even consider your song for a ring tone, you need to take your trimmed song in m4a format and rename it to m4r. I is identical to m4a, but foe some strange reason it needs to see the different extension, no exceptions.

    There are a few apps for iPhone that also trim the song for you, but you still need iTunes to import the song and then add it back as a ring tome. Might as well do it all in iTunes.

    MP3 Trimmer is the best option, because it edits the file "in native mp3 format", without decompressing it and then RE-compressing it back to mp3.

    Because mp3 is a "lossy" format, each time you decompress, edit, and the re-compress there is a chance that data will be lost in the process.
