Just got this email from Vodafone:
As a Vodafone Ultimate Pack customer, we've some great news. By 1 July 2010, we will give you a whole lot more data - and we wanted you to be the first to know. We can't say any more for now, only that you can look forward to getting some more data bundled into your existing broadband plan, at no extra cost. We'll be contacting you shortly with the full details.
It's just another way for us to say thanks for choosing Vodafone.
So let's put this in Laymans Terms - Vodafone is giving out free data to it's customers (or at-least some of them) - Cheers Vodafone!
