that option u have to pay.
i can get songs to the phone, but it wont let me select it as a ringtone. in the ringtone menu, it says "my contents" its not downloaded.

My content and other 3 list r the only ones i can select to choose ringtones from..

from the music file directly, there is no option for make it as ringtone.

so i need help here..

even when i use bluetooth to download the file from my pc to phone, it still wont let me.
