Just as Apple appears to be readying its music streaming service and Google just announced its subscription music servicePandora Radio has released a sturdy update to its iPhone app.

Users can now publish Now Playing activity to Facebook as it updates, similar to Spotify or Rdio, allowing friends to interact with the music you enjoy. Sharing individual tracks and stations to Facebook, Twitter, and email is built right in now as well.

Pandora 4.3 also includes a handful of UI improvements that greatly improve the native feel of the app, including the ability to tap the album art to reveal track information, but the new features and improvements are only available for iPhone for now.

Pandora 4.3 is available on the App Store now:
