How can i use my mP3 or WAV files as my voice mail greeting?

[odaoud]

I have a music file saved as MP3 / WAV and I want to use it as my voice mail greeting. Any ideas?

Other than playing the file my computer and holding the phone to the speaker.

I use a BlackBerry and iPhone

Thanks

The voicemail has no way of using a sound file stored on any of your devices. You'll have to play it loud enough for the voicemail to hear it when you go to record the greeting.
