I am trying out the 30-day free trial premium account, and have downloaded the Spotify app to my iPhone 3GS. Playlist is turned to be available offline and synced. However, when I launch the app on the iPhone it requires me to have an internet connection to login via Facebook or Spotify details, so I can't even get to my playlist. How can I get around this? It defeats the purpose if internet is requried to listen to offline playlists!
