Just thought I would share my experience...
BT have just called me trying to sell me BT Infinity. But they did not call it that on the phone. They just said "Faster Internet". I then asked was that BT Infinity, and the woman said YES.
So it looks like the time scales for roll out have been put forward again

Originally it was December, then March, and then it disappeared from the website a roll out date.
I asked if my "Special Deal" that I currently have can be moved to BT Infinity, and she said no it will be the advertised price. She did quote the price but I cant remember what that was now.
SO I said I will have to wait until my current special price is up, as I cant justify the price increase.
She said they will keep my details on file and call me nearer that time. I replied fine

I did ask her if this call was in reply to the pre interest thing that I was notified when it was available on their website, and she said now. So Im wondering what's the point of that!!!
Oh the area Im in in Reading central.
Hope this is of use.... so you may be getting a call soon as well
