Already with vodafone, end of contract but how to get new contract with same number?

As above really as iv heard that you can only use PAK code to keep the same number when your moving between providers, not if you want to stay with the same provider and just get a new contract instead of upgrading.

Thing is though I want to try and make some money out of it using topcashback, reason im doing this is because I want the new HTC Desire HD
