Thanks every one!

My next problem is how to get this upgrade! I called NTL today but the lady on the phone at NTL towers said she could not do it and it needed a ISP PNP tranfer of codes(i have no idea what this is!), and you can only get that from an engineer or a web upgrade. She said to look at the web site and try and do it from there, otherwise she could not help.
Any ideas?
She also said there is an upgrade fee of £20!

is this correct!?
Thanks again
