He needs to check the ID3 tag. If the title is not in the ID3 tag, it won't show up. To do this, either convert the .ogg to an MP3 and use a program like MP3Tag ( mp3tag.com ) and change the ID3 info. Then either leave it as an .mp3 or convert it back to .ogg.
Then he can place it eiter, like Rarewolf said, in the \system\media folder or on the SD-Card into \Media\Music\ringtones
Works perfectly here !
