i tried to use iRinger, i even managed to send it to iphone, but then when i want to choose the ringtone, it doesn't appear at all. so basically i m using iRinger to cut out the section. was so frustrated figuring out how to make custom ringtone until i see the above post.

hmm, i wonder if the new 3G iphone is also so troublesome, and only less than 40sec, it can't even be 39.5sec.
