Motorola Droid X :: SBF & Bootloader Versions?

When all of the leaks were kicking around, I installed the leaked 2.2. I used the 2.1 SBF to restore the phone a couple times during my playing around with various ROMs.When the full 2.2 SBF rolled around, I used that to upgrade to 2.2 rather than accepting the OTA, partly because it was easier to do that than it was to roll back the leaked 2.2, then accept the OTA. However, it looks like, during this process, my bootloader never changed. I'm still at 30.01. Intuitively, I guess this makes sense - you can't update the bootloader from within the bootloader. However, there have been a lot of questions surrounding the new 2.2.1, bricked phones, and bootloader versions. I know the theory is that it's just from wiping data but nonetheless, I'm wondering what my options are or if I need to worry about it at all? Can I SBF back to 2.1 and accept the OTA to get a recent bootloader, since I still have the 30.01 bootloader version? I guess there's little harm in trying since I could always SBF back to 2.2, but I'm just wondering if I'm asking for trouble.
