No, i got a letter through the other day, they are upgrading all existing 1mb customers for free of charge, ney less than they would pay normally, up to 2mb,
Usually it costs £28.99 a month, and they are reducing the cost to £24.99 and upgrading you to 2mb without you doing anything.
This is, aslong as you are within a set distance of the exchange....
Woo 2mb here I come :P ..........
Got the letter in my hand, so any more info needed give me a shout!
