Video streaming with Orb

I got fed up with the kids' refusal to sleep last night. Moreover, hubby wasnt helping the situation much as he just wanted to keep up with the latest political news at his favorite site. What else can i do la, sigh. So, i took my O2 to bed and watched video streamed to it from my pc using Orb. I've set up a private channel for my Orb friends to share some of my videos. I find that i can only watch it over wifi, but not 3g. Damn, when can we ever get reliable connection? Paying so much yet not getting our money's worth.
