Howdy ladies and gents, i have a noose in one hand and a shotgun in t'other!

I have trawled through endless websites, archives, faqs and unlocking lists and i just cant seem to find any earthly way of unlocking my new god forsaken 6700 slide!! It is currently locked to UK O2, and i need it on my vodafone contract!!

any help will result in you being elevated to near god-like status in my eyes.

Thanks for anything you can do!!
