Yo, we got ours when we went to Bradford barrio festival, wife was haggling me to get it, so we signed up and got a free box to watch. He forwarded the form which I signed to abs-cbn, then a couple weeks later it was up and running.
The unit it self is connnected to your broadband internet. I've set it to use wireless which is cool.
Subscription is £19 per month. We got 1 month free too.
So best bet is to go to a barrio festival anywhere around the uk and get your free box there and then when you sign up.
