I got a letter from BT recently saying that infinity 2 was now available in my area. I have had a look on the website and it tells me that I could get a download speed upto 62mb. Checking what I can upgrade to with sky and they are saying I could get speeds upto 40mb; the highest sky package isn't available. I am confused as I thought the networks would offer the same speed and it was down to pricing. Any help understanding the differences would be appreciated.
