How do i transfer downloaded ringtones to my samsung cell phone?

I have Samsung t609 and have downloaded few ringtones. Can anyone help telling how i can use these ringtones for my phone.|||I have the A707 and haven't figured it out either


I do have the cables and software|||first of all, you`ll have to have a usb wire or like a wire that connects to your phone to the computer, and that wire helps transfer the music to your phone. you can go to a phone store and buy a samsung usb wire, but it depends on the brand phone you have cause there`s a whole sort of wires.
