NPR launched NPR Mobile at http://m.npr.org/. This mobile friendly site lets you either call in (voice phone) to listen to a show (not recommended IMHO) or listen to an audio stream (great if you have an unlimited data plan or WiFi). I tried it over a relatively slow EDGE network. It took a while for the audio stream to sync up, buffer, and then start playing. But, once it did, the sound quality was good and I didn’t run into any oddities. Navigating through the large and rich NPR site was quite easy on a WiMo6 T-Mobile Dash smartphone.
