Thanks Salami1_1
The email address you posted appears slightly wrong, but I think I got it. I'm not holding out much hope as none of the unlock services I've tried can do it.
I think my only solution is by the file method. I need to dump the root file system in the phone and search for the code in a nv file. So far I only get a partial dump using Stunes.
Hopefully someone here has some expertise with these samsung S8500 phones. I see there is some reflashing info here.
