I wanted to share a little tool that I originally developped for myself which can help to unlock your HTC One S.
Here you can find the tool (in french):
If you have any comments, or ideas to improve it please let me know and maybe I'll create a new version of the tool
-> I'm posting using this account, which is the one of my brother so that's why in the app in the top right corner the creator's mail is because it's my mail adress...
EDIT: here's an english translation of the tool: , as someone asked me for it by mail
EDIT 2: here's a dump from my HTC One S, I edited the file so that the informations match the example given on the thread I used to calculate the unlock code ( http://forum.xda-developers.com/show...17&postcount=1 ):
