*.bin to *.re, *.rttl or other format

Hie there, i've download some of my songs from my Received Ringtones space with GNOKII.

But i'm having trouble of converting it into *.re, *.rttl or some other format that are suitable for PPM MAnager or PPM Fix.

For your information, my downloaded song is in *.bin.

So is there anyway that i can convert it? Or is there any way that i can add it to my phone ( after 1-35 original songs and b4 those empty space?)

Please Advice
