Just got a deal myself . also a long time customer (years out of contract).
My intention first was to ask if they could send me a free router .. apparently not , but the nice lady (english!) said if I upgraded to the 50meg service a wireless N would be thrown in free , they would waive the £40 instalation fee , but there would be a one-off connection charge of £20 .. and my monthly bill would go down by £2!!
I think there is a web page about this deal for existing customers on the Virgin web-site somewhere .. but my bill actually going down was a nice surprise!
The rest of my package btw is standard phone line + free TV with it .. the only downside is being back on a 12 month contract , but that's no real problem for me.
It's being installed tomorrow .. so nice one Virgin!
