Are you referring to unlocked bootloader or SIM unlocked? To do the OTA update, you have to relock the bootloader yourself before the OTA update will work. If you're referring to SIM unlock, if your phone is already SIM unlocked, the OTA update will not alter that, it will still be SIM unlocked after the update.
