Correction: Our earlier report misstated the progress of Rhapsody’s iPhone app. The Rhapsody app for iPhone has not yet launched. RealNetworks (NSDQ: RNWK) announced in a company blog that it would be submitting the app to iPhone for approval this week. That doesn’t mean the app will ever launch on iPhone and, while Apple (NSDQ: AAPL) told the FCC last Friday that it approves 95 percent of apps within 14 days of being submitted, some apps take longer and some are rejected.

In Rhapsody’s favor: although Spotify, which is not a similar service reportedly has been in the process since July, subscription service Sirius XM (NSDQ: SIRI) already has an app in the iTunes store. And by going public, including a video preview of how the app is meant to work (embedded below), Rhapsody puts pressure on a company already in the spotlight with the FCC over how it deals with competitors.
