I've got an O2 Xperia S too. Just ask O2 to unlock - it took me around 10 working days to get it unlocked.Sorry if this is covered, I've searched and it doesn't appear to be. I've just got hold of an O2 locked Xperia S, what's the best way to get it unlocked? Asking O2?
Looks like it was a bad idea though, as the bootloader on this one can't be unlocked![]()
Bootloader will remain locked though, nothing can be done about that.
