How to format MP3s to be cell ring tone?

[PulpMind]

[ramble]
My phone (Motorola v400) plays MP3s as ring tones. I've downloaded some of the crap on Cingular's website as tones, and, while amusing, none of it really fits me.

So I have this song, Banana Phone, by Raffi... Using Logic for the file cropping and iTunes for the mp3 conversion, I've edited it down into what my phone says the mp3s are that it's using for ring tones [ 64kbps, up to 15 seconds long and 150Bytes]... emailed myself my newly edited Banana Phone song (I even took care to filter out low end frequencies), and it sounds like CRAP. not only that, the phone says it's 8kbps and some other audio format...?!

So to be short...

How can I edit and/or what are the requirements to have an audio file work as a ring tone in my Motorola v400 phone?

Thanks Much!

i have a V265... first there is this company... www.tonethis.com... they let you upload 2 mp3s for free... i just picked out a song used thier software to crop it and it sounds great. I used Right place wrong time by dr john... no one has my ring, and thats the way i like it... but dont worry about editing the actual mp3, just pick one you know would make a good ringer. If you dont know what i mean download that song... i mean go buy it on itunes or something.
