Some days are better than others...
I managed to break several of the small metal pins in the sim reader, don't ask me how but I did it =(
I unmounted the phone and it's really just a small circuit board linked to the motherboard with a single ribbon
I have googled for where to find this spare part but no chance so far
Would you know where I could find this part and help me revive my Nexus S ?
Thanks for your help
