I just spoke on phone to a manager in ntl HQ Glasgow, although he didnt know when the glasgow upgrades will go ahead he did admit that other parts of the uk have already got the wheels in motion though.
He also says there is NO mention of any admin fee (£25) and caps wont be enforced heavy duty like some of you are saying, infact caps have always been in place with ntl broadband its just that they dont enforce them too much unless they find someone ripping the crap right out it, I.E- running a buisness using ntl broadband etc, they will come down heavy on idiots like that.
So I hope this info helps ease some pain till your upgrade comes along, I cant wait for it
