Here's a screenshot of it as seen in the iTunes store:
It was made available for free so people will have a free option for listening to WRNI on their iPhone. At the time the app was made, there was no free iPhone app that allowed adding a custom streaming radio URL on the phone. The only options were apps that cost money. Since this is free public radio, the radio station wanted a free method for the public to listen.
A friend of mine works at the web design company that was developing WRNI's new web site. He knows I'm getting started writing iPhone software, so he asked me if I'd be interested in making a free app for WRNI. Less than a week later we had a working app submitted for review in iTunes and today it is now officially available for download in the iTunes store.
It's a happy day for me today.
