How to put my Spotify playlist on my iPhone?

I have an iPhone 4S with Spotify installed (I have a free account) and I want to put my Spotify playlist on my phone. I thought there was a way that I could put the songs I have starred inside the Spotify app on my phone, but it won't work for me. I can't figure out how to do it.

Please help:/

Thanks!

Added (1). I am logged into my Spotify account. There is an option to sync my music, but that's where I get lost.

Added (2). Oh, nevermind. When I click "Playlists" inside the app, I can see the music I starred but I cannot stream it because I am not a premium account.

I tried this before they updated the app, but not on the most recent version of the app. Spotify devs must have just fixed it.
