If your cell phone has a browser available, then use that to connect to the Internet. From there, just enter the address of the MacGyver theme song mp3 from the sound page. (The MP3 file itself) And you should be able to download it to your phone and then look under your files and apply it as a ringtone.
I went ahead and got the MacGyver ringtone from the site here for my phone and it ROCKS! Thanks a lot for putting it up Rockateer!
