We have successfully rooted the Virgin Mobile Security Update now. It is safe to install it. Once you have installed it, you will have the latest radio for the cell phone towers. After installing, follow the steps in the thread linked below to root it again, then you can restore your current ROM and still have the new radio.

You will probably be receiving a text message soon informing you of a security update for the Optimus V. You would be wise not to install it for now!
This update will remove root, replace your custom recovery, and install a radio image that is currently only supported by the software version it comes with.
Give the devs a week or two to dig into the package, and we may come up with something usable.
Note - Do not install the radio if you already have the touch recovery installed!
