Saw this in the London lite paper the other day.
Go to http://www.three.co.uk/lite
from there you can see the link for the Nokia 6120, with 700 xnet mins or texts.
Comes with additional 300 3-3 calls, and skype.
Well aware that not everyone likes three for CS/coverage... but looks pretty good to me..!
Guessing you cant use quidco as the link is different.
