Found this app the other day that allows you to watch the above channels and a few more on your phone ( can't comment on whether there is an iPhone alternative. No sign up or anything sneeky just down load and pick your channel and away it plays (about 10 sec delay from what's actually 'live' on TV).
The app is called 'filmon.tv'
