Streaming over the net using the iPhone and 3G

Hi all, I want to first apologize if this topic had already been discussed. I guess this could be more general for streaming over the net with indeed any mobile device. I'm pretty excited because I never really knew if there was a way of streaming over the internet with my iPhone using 3G without any specific links for iPhone or mobile devices; I thought there must be a way but I hadn't discovered it yet. Yes i've been an iPhone user for years so I'm very behind in this aspect. So, wanting to stream outside before, I went to the aCBradio world site (to be specific) and it gave me the usual options for listening with winamp, media and reel players or "other players" high quality or moden; I first chose the high quality but that didn't work, so I chose "other players" with modem, and the stream (the world blind union to be exact) played perfectly. So, i guess, to turn this into a question, if there was a streaming site that simply gave one listen link, would that link work with even the iPhone? How do you others go streaming on the net using your phones with 3G? I'm not so much interested in wifi atm as I don't have that option at the moment. Thanks all and sorry about this backward post.
