I have runner in my mobile phone too!
Where can we get that ringtone?
Runner is one of my top Macross songs too
What I did was Convert the song from a CD to Wav file then into MP3 (lowest quality mono, besides, it's going to be put in a cellphone). Then, ofcourse, I got myself a USB data cable to make ther transfer. My phone is a sony ericsson K500i.
