iPad viewing is possible via the world tv plus or global tv HD app. They always have those channels live.
Annoying ads and can be a pain searching through the various channels to find it. But if you can source the right one the picture is usually spot on! You just have to repeatedly close the adverts as you work through. I have always got the televised games on these apps and even the PPv Sky boxing etc. Usually on one or the other of the apps.
I binned mine a few months ago, BT are atrocious robbing bastards. When you ring up they will offer you it for a lot less though they wont tell you they can hike it up whenever they feel like it like last year, mine went from 16 to 24 quid and was stuck with it for 4 months after
