Morcheen, new and existing customers pay the same. New customers may get free install but didn't you when you signed up? What package are you on?
I think its costs 4-5p per minute when you call Sky, unless you have the calls package with them which would then make it free. If you don't want to call them, email them via
www.sky.com
Dojj, that's the box I'm getting soon.
