Samsung SGH-T201g

I purchased this phone from Net10 and I can't download the ringtones I want. Net10 said I am limited to the ringtones on their website. What a bunch of nonsense! I also can't get on the web. I can only go to Net10's web site according to Net10. This is also a bunch of garbage. This is false advertising in Net10's part.

Is there anyway I can get the ringtone of my choice for this phone? I just want the Andy Griffith theme song(the original, not some fake digitized junk) on my phone. Thanks.
