ok not too sure about the best deals, but can i ask what happened with your orange contract? two of my flatmates have realised they haven't got orange signal in our new house! real pain for them, they have about 1 bar in a certain place in the kitchen but that's about it.
How hard was it to get your contract terminated? Can't imagine its very easy, but i think not having signal is starting to drive my mates mad!
cheers
