Some skeptics think that the mobile network can't handle such applications. In fact, it's here now. And it only requires a fraction of my 6GB monthly bandwidth allowance, assuming you're not listening 24 hrs a day. And it seems to be acceptably reliable (it just plain works). And the 3G coverage in areas where I'm actually located (inside my house, inside my office, inside my car, driving behind hills) is fine.
This technology does actually appear to be perfectly 'Ready for Prime Time.'
Here is a screen capture of my iPhone playing BBC World Service.
