How to convert music from YouTube on to IPhone 4?

I follow all the directions, and it says it downloads, but I have no idea where it is! Because I check all the music folders and its not there!

Downloading a software will work the best

I suggest getting the "Free youtube to mp3 converter" from "dvdvideosoft"

i use it all the time, the down load is small so it won't really take long.

Then once you install it, its really easy to use and will even let you choose the quality of the song you want to download.

when its done downloading you just put it on itunes and sync it.

Hope this helped.
