Since its a rooted zip, it will upgrade the software to VRBMF1. Your baseband (Settings/About Phone/Baseband) will still read VRBLK3 so you'll need to flash the firmware that Sandman-007 just posted about. As I said before, this will only work if you are rooted AND unlocked. If you haven't unlocked your bootloader then do not try this method.
To answer your initial question in your first post, you can take the OTA which will unroot your device. You can then use Casual by beanstown106 to root/unlock again.
