Well I got no response but I tried it anyway.
A free SE W580i on a 12 month free contract.
I did go through fone-shaq and they did link me to the right place and I have got the phone.
I think the catch is that you have to remember to send off your bills at the right time with anything else they ask you for.
They are probably hoping I will go over my free allowance.!.
but i won't and I WILL remember to send the bills.
Easy win for me (I hope)
