Hi, thanks for your reply, I have a couple songs I can try on my iTunes already. Could you list those steps for me? Thanks again!
Just make sure the song is the right length (< or =30 seconds) and sounds the way you want it. If it's not use iTunes start and stop times to make it so it is. In iTunes you will need to have your import settings set to aac.
Create an aac version of what you want as a ringtone (Right-click on the tune and select "Create aac version")
Navigate to the aac file and cut it - then paste it on your desktop. Change the file extension from m4a to m4r and drag the renamed file into iTunes. It will be recognized as a ringtone and you have it.
Now just clean up the left over reference to the aac file in iTunes and change the play length back on the original (if you changed it).
