Once again, they are claiming it is a 'dual core' processor. That's wrong.
Also, I would not call this reliable information at all. As soon as vodafone have the tariff costs, they will release that info themselves first.
It is a definite that they dot have a solid release date, hence no mention of one, and they don't have finalized tariffs, or they would have announced them.
Im tired, but can also confirm, as its the same with all of their contracts for similar priced phones, the phone will not be free on £25/month contracts even with little included like that one.
The phone will only be free from 30 or 35/month is my educated guess.
So you can instantly discard this sites info.
