Im not sure what that link says about putting ringtones and walpapers on your phone but i van help you with putting ringtones on your phone.
first try to get a converter such as the "IMtoo 3gp converter" (which you need to convert to the .3g2 format.)
Next, take a song you want and get a program to cut out the certain part of your song that you would like. (try not to make it more than 35-40 sec.)
after that is done drag the song into the IMtoo converter and convert the song to a .3g2 format which is accepted by all sprint phones (at least most, i think).
After the song is converted find the folder on your chip for your phone that the pics of your phone are placed in when they are put on the chip.
Put the .3g2 format on the chip in the folder that stores your pics .
you then could choose that song as a ringtone.
if there are any other questions please ask.
Thanks, Jack
