You would need to either contact O2 (if you have a friend etc who is an O2 customer) or use an unlocking site (like Horizon Wireless).
Thank you for your help MidnightDraven, that is what i thought might be the case, getting it unlocked is no problem, but just thought i would find out for definite if it was still O2 as the Vodaphone thing did confuse.
