RORO01  All this application does = you taking your iTunes created MPEG4 AAC audio file, changing its extension from .m4a to .m4r and then double clicking on it. Therefor, it is only useful for batch processing.

RORO01  DOESN'T WORK

Dragged an AAC ringtone file onto the window and the only thing the application did was to open iTunes. Nothing under the Ringtones tab or anywhere else. As the developer suggested, Apple made this program obsolete. iMac Intel 10.4.11, iTunes 8.0.2

IAMASWISSGUY  Awesome! This does its job perfectly... and has done it without having a new iTunes version break it for a LONG time.

Simple and convenient. One thing I would like added, though, is an option to just take the first 40 seconds of the song and use that as the ringtone. Currently, I have to use Quicktime to trim the song and export it back to an MP4.

Great and simple app, nonetheless.

GERBER  It works fine with the iPhone 2.1 firmware. Just made two ring tones.

Easy to use, just drag & drop. I only wish it could handle other sound formats and just convert to AAC in the middle. Instead I have to use iTunes or Quicktime Pro to do the conversion.

DRZOOM  i updated the iPhone with the new firmware 1.1.1 and now the program doesn't work anymore even if I still have iTunes 7.4.1

MARK.ANDERSON  Another great app from Rogue Amoeba, and free no less. I'm guessing they'll have a 7.4.2 compatible version by the end of the day.

JOHNNY ROCKET  anyone know if this works with the new iTunes 7.4.2?  
(Version 1.2)

YUNFAT  It just works. Thanks.

THEMACJEDI  It's a one purpose app that does what it says.

Worked well for me.
