Proton iPhone App
To stream On Demand mixes, the live stream, and more.
@Rolphus: Try streaming Proton Radio on your iPhone by typing in "http://www.protonradio.com:8000" in your Safari browser. The iPhone app is currently underway now too for additional functionality :)
As I now can't listen at work (where I do most of my listening) due to an internet usage policy change, but have very good 3G signal, this is the only way I can listen to Proton regularly :(
