How to put music on my iphone 4, for free?

Can you give me steps please, thanks.

There's an app in the top 25 free… I think its called free music download.
Anyways Install this app.
Go on google with the app.
Write the name of the song you want and write "zippy" or "hulkshare" at the end of it.
Click on the 1st or 2nd link, there should be a download button, click it and your song should download and be in the apps library.
Only downside to this is that you always need to launch that app, the music does not go in the music application.

Download an app called "my media" it will then show you a site on how to download the music. The app is where you listen to the music on, and it works like the iPod on your phone. You can close the app, and music still plays

Go to the appstore and download an app called MusicTube Then you can search for music you want to cache. You need internet to get the music but after you click it, you don't need internet again to play it. Hope this helps.
