As a bit of a training in using Qt and Gstreamer together I made a Radio X3M app for the N9, first mainly for personal use but maybe there is one or two Radio X3M listeners with a N9, who knows.
Submitted it to QA today, it is also available as a direct download here. Sources are are in git here. The most interesting part is probably the QML Gstreamer RTSP player element, here. It uses a bunch of elements that are connected to various UI elements for Volume, Equalizer and Surround.
