Retrieving ringtones from a Samsung T100

anyone know if there is any way of retrieving a ringtone stored in a Samsung T100 phone?

i've just changed handsets to a D500, but REALLY want to keep a ringtone i had on my old phone. Softmobile doesn't seem to have any way of transferring the tone from phone to computer (only the other way around). Does anyone know of any other ways (other software perhaps) of achieving this.

thanks
