Relocking after unlocking (on verizon)

[rothgar]

I hate to start a new thread but I have been searching and even posted in the "hard-spl" thread but didn't get a response.
Here is my question.
I have a demo TP from Verizon (till Monday) and I really want to try out a couple of the cooked roms before I make up my mind on the device. Only problem is I don't want to unlock the device and then give it back to Verizon that way.
Is there anyway to relock the device after installing the Hard-spl?
I know there is a way with my current titan so I figured I'd ask but haven't found anything (especially not for Verizon on the issue)
Thanks in advance!!
