This method does not work for W580i, may work for other models
For the W580i branded by Rogers Canada, simply convert your ringtone file into mono (very important) .wav, and place it anywhere into your phone (the "ringtones" folder for convenience), select more -> use as -> ringtone, and you're set. Simple as that. Yes I just tested this a few minutes ago.
Thanks SO much for the person who mentioned the conversion into .wav file!! I'm so happy I can finally set my own tones and not use the ridiculously stupid default ones ^^
