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 ianis58[at]gmail.com because it's my mail adress...
EDIT: here's an english translation of the tool: https://docs.google.com/file/d/0B6cT...RHa0ktekk/edit , 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 ): https://docs.google.com/file/d/0B6cT...FMUUg4dzg/edit
