As far as I'm aware, being unlocked and being rooted are two separate processes on this phone. You don't have to have one to have the other. I've been rooted and locked, rooted and unlocked, and unlocked with no root. Hope that helps.
And I haven't had any problems with the one-click root and unlocking or sbf-ing back to stock.
