I believe your phone runs on the Symbian operating system, and as a Nokia product it will probably have a link to the Nokia OVI store somewhere in there. If so, just go to the OVI store and look for a free app called Internet Radio. Download the app, and away you go. It knows about most stations already, so you can do a search, or you can input the URL stream directly if you know it, if the one you search for doesn't come up.

It works fine on RNI's 32k stream, and many others on my NOKIA 5230. I'm no expert, but as far as I know this app doesn't use flash anyway.

The only downside to listening to radio on your phone is that it can be quite costly. So if you've got Wi-Fi connectivity, always use that in preference to the phone network.

Hope this helps.
