Which code's to try for 6230 unlock?

[john642]

I have a Nokia 6230 on Vodafone which I want to unclock to use on o2. The NokiaFREE software generates 7 codes, but it looks like you only get 3 attempts before you need a cable! Does anyone know which code is the most likely to work?
Cheers

Hi M8
I always use code 7 and never been let down yet, sometimes you have to put a non accepted sim in if the code just stays on screen
