I have managed to survive since Sunday on the internet via my phone, which sadly struggles to find a good signal in the area. But now I have BT Infinity and man is it awesome!
To be fair I've never had great internet before, but having FTTC really does make a huge difference to what I'm used to.
As well as that BT Infinity do an offer where you can have a trial of OnLive for free for three months! Which you can find out more about here, as long as you're a BT Infinity customer you can take advantage of it, plus they don't take any card details either so you won't have to remember to cancel anything.
