Nokia 6230

[jb719]

I have a nokia 6230 on o2. Which gen do i use to unlock the phone and also which code (1,2,3,4,5,6,7)?. I have used the online calculator with ASIC 6 and box 32821. I have also used an offline calculator also with ASIC 6 also with box 32821. (Both Calculators gave me different codes).
The phones firmware is:

v 04.44
21-09-04
rh -12
gsm p1.1

I have unlocked other phones which have worked at the first or second attempt. But this one is being a real pain! and i dont want to waste any of my code attempts. (I have used three).
Any help is much appreciated.

Thank you

Well... using the standalone version of nFree calc, I'd say a good option is to try generating codes with GEN ONE... but use the search engine on that phone to see which code must be used, because en UK networks some providers use first codes, others fifth and others seventh.
