Iphone 3GS 4.3.1 – 05.16.02 – unlock

From what I am reading i am guessing I have bought a dud?
Bought a second hand Iphone 3GS today, it is on o2 and I need it to be on Orange. Any ideas how/if I can get this done?
Any help much appreciated…
Thanks

Only solution (but not recommended) is to upgrade your BB to iPad BB 06.15.00 and to be stucked there..
More about that BB, read here…
