[Q] Unlock BL for ICS

I have an Xperia S, which was carrier locked on O2 , then i unlocked it, now i updated it to ICS via flashtool , but in system configuration, it says Bootloader Unlocking : No ", so do we have any chances to unlock BL even after getting ICS on our phone?

I had the same situation I went to the guy, he took off me simlock and unlock the bootloader unlocked this way :laugh:
Only removing SIM-lock is not enough.
Depending on when your phone is manufactured, it may be possible. Check the manufacturing date, it is under the battery. If it is before 12W11 (year 2012, week 11), then it is possible. Otherwise, no.
There is 11W36. Do you know some tutorial for unlock this "unlockable bootloader" ?
isn't it dangerous? does it work?
I did it via wotanserver, but it's not free.
No homemade way??

Sim-locked device recently unlock flash unlock version of firmware

Is that possible? I just recently unlocked the device from the carrier since it is out of contract now. The carrier that was lock is a little slow on updates but the unlock version is not. What's gonna happen if I flash the unlocked version on my device? Will it brick?
