How Do I Download Tones ? ? ?

This is my first cell phone, ever !
I have a Samsung x427m and so far it is terrible.
I hope they are not all this way.

The display is too dark when outside, the free tones choices you get
are terrible, and the sound is way too low.
I've adjusted the contrast, the maximum sound and still no luck.


My question is.
What is the procedure to get a MP3 dial tone that I just created on my
PC into the Samsung x427m?
The manual does not describe how to download extra sounds.


Do I need a special cable, software or both?
And if I do, what are the step-by-step instructions on doing so.


Thanks,
