Does anyone have a Sony Xperia X who has yet to unlock the bootloader?

Apparently if you OTA update to version 34.3 it *should* remove the need for Emma/Flashtool when installing Sailfish X.

But once the bootloader is unlocked you stop getting OTA, so none of us have managed to test it yet...

So the procedure is to OTA update all the way, then unlock the bootloader and install Sailfish X

Anyone willing to try this out for us?
