Click above for a preview of Spotify's iPhone app. It's been submitted to the iTunes App Store and should be available within days…as long as Apple approves it.

The Spotify iPhone app lets you access your previously created playlists and best of all, has an offline mode which syncs tracks to your phone. That way, getting on a plane or on the underground won't interrupt your music.

Song playback resumes when you return to the app and you can search for new tracks within it. Changes made to your playlists will show up on Spotify on your computer too.

Our favourite feature (aside from the genius offline mode) is skipping tracks by flipping through the cover art in a Coverflow style.

As soon as the Spotify app hits the App Store we'll have a full hands-on test for you right here.
