If you want the closest VM firmware to the current Sprint version download and flash the PG86IMG.zip file from this post through the bootloader.
A lot of people on this forum are still running the radio and PRI firmware from the original "fix everything" thread but that was a temporary fix until VM released the OTA. If you have any problems with the OTA firmware updates you can always go back and flash the "fix everything" versions, which are pulled from two different Sprint GB builds.
