Yeah, the fact that most mobile devices these days lack radio functionality is something that's always baffled me, especially now that some phones are being equipped with TV tuners.
I tried once, with my then phone's FM radio, to listen to my usual BBC station on my 25 minute commute train journey. I gave up (too many tunnels, bridges, cuttings, with poor or no signal), and went back to my MP3s. I certainly wouldn't want to try TV!
