I got this letter too. All well and good, but how much do you actually pay for 4mb just now?
I pay £25 a month, so to be fair, it's being upgraded, but only because £25 a month for 4mb is just silly, and they need to make their customers feel like they're being treated well.
They're only doing it to try and make sure their customers who dont really know the difference, dont go find better/cheaper anwhere else
