Nextel i730 .wav files - can I download?

Hi guys, I have an i730, and I just (yes, JUST) recieved in the mail my PC to phone data cable (to update my GPS, which I didn't get to work anyhow...).

My question(s) are: I figger that, somehow, I am now able to put some of my .wav files (from my iTunes library), onto my i730 as ringtones. Am I correct? Can this be done? I want MY music to ring on my phone, not THEIR cheap sounding, $2.99 ringtones. How can I do this?

Also, what the heck is an i285 Boost card? I see threads referring to them, but honestly do not understand what they are.

P.S. - I need your answers to be for "Dummies Only", as I'm not to literate in these fields. Any help would be so much appreciated. Also, if anyone has cool, working tweaks, I'd love to hear about those also. Feel free to email me at:
raintownmusic@yahoo.com Please put "i730" or something in the subject box so I do not delete it. I thank you all in advance...
