N80 on O2 Original product code????

If you'd read it all properly you'd have noticed that your original code is written on a label on the phone under the battery.

And *oopsie* on your double post btw 😉

I would advise you to change back the Product Code NOW because if your handset develops a fault you might not be able to change the code before taking it into an NCC, and if they notice your code is wrong your warranty will be void.

P.S. As stated by others, the original produce Code: is on the label behind the battery on all Nokia phones.
