Vodafone has this new promotion at the moment 30 days of free music:

The blurb goes on to say you have sign up, they will send you a link of the song you can download (you can't even choose the song!!). At the very bottom you see the real clincher of the deal, "Standard data charges apply to download the free track"
So vodafone what you are saying is the free track is not free?
