What OS version are you using? I just purchased an iMac that came pre-installed with Leopard. Originally, I was using iToner to upload custom ringtones, but I found it much easier to customize and upload them to iTunes via Garage Band and then sync the phone.
 
This did not work for me....
It worked for me for about a dozen songs. Here's what I did:
1) Choose the mp3s I wanted to use in iTunes
2) Converted each file to AAC (you have to have "AAC Encoder" set as your Importing preference in iTunes
3) I trimmed each file using this method:
Don't forget you can trim tracks in iTunes itself...

Do a "get info" on the track in question and go to the "Options" tab and use the "Start time" and "Stop Time" fields to confine Playback between these two points - this method is non-destructive.

If you want to permanently "crop" the track, you can (with the track selected) go to the "Advanced" menu and select "Convert Selection to..."

This will create a "cropped" copy of the track.
4) Then I right clicked on the resulting file to "Show in Finder"
5) Finally I changed the extension of each file to .m4r

Works like a charm. I'll have to try the GarageBand method as well.
 
I am using the method of changing m4a to m4r, then drag/drop into iToner.


I figured out, all my iTunes bought songs were unable to be played as m4r (ringtones). But all the music i have DRM free plays as a ringtone no problem.
 
Does anyone disagree with the proposition that the now available Garageband method makes iToner obsolete anyway?
