I know BBC iplayer works fine but what about the others? I haven't got the Internet wireless at home I only have the Internet on my phone and I have free data.

There are free apps available for ITV Player, 4oD, and Demand Five... however I do not know if they work over 3G, or if they will only work using WiFi.

The apps are free, download and try them.

As far as i am aware, the only one to work over 3G is the BBC Iplayer. the rest of them all require wifi access.
