How to download music for free on my iPhone without buying them on iTunes?

I have an iPhone4s

Find a site that has free music. Apple is about making money. They prefer to lock you into iTunes for everything, then they can control everything you buy.

You can always download songs from YouTube using listentoyoutube.com and then dragging the downloaded file into your iTunes library. It's time consuming but it gets the job done.

Since this video it's online

everybody it's getting free itunes codes, I haven't tried it yet but it looks like is working.

I do this all the time, I take my mp3 songs and select and add them to my itunes list, then add to the iphone. Really simple.
