Whomever told you that the boot loader couldn't be locked is mistaken. If you flash a non-developer bootloader onto a developer phone, it now has a locked bootloader. Unfortunately, there's no way to undo that until (unless) the developers figure out how to unlock the bootloader.
Install the "Phone INFO * Samsung *" app from the play store and open it. What does it say for the Bootloader Version?
There's also a "Phone Info" app that can display the bootloader version as well.
My Android devices:
vzw Samsung Galaxy S4 stock NC5 rooted
Samsung Galaxy Tab 2 10.1, also stock but rooted.
VZ Droid Incredible 2 rooted but otherwise stock.
