Well yeah, that's kind of my point though...having a .596 SBF file would be a LOT faster than SBF'ing back to 2.3.340, then getting the OTA to GB. Granted, a lot of people who root won't care about going back to unrooted stock...however, a big reason to have it available as an option is in case if you need to bring the phone into VZ, so they don't see your phone rooted/ROM'd and make a note in your account.
There is a SBF for official unrooted GB. It was released late last week. Download and add it to your Droid X files. I don't ever plan on using it b/c it is the unrooted version, but like you said, it is nice to have, just in case.

I had my droid x rooted and the other day i installed the system update like a retard, can someone help me figure out how to re root? Im new to all this so im in need of a little help. I have the Z4 Mod app and tried the temporary root but it wouldnt go past the exploit screen. Before i did the update i had my phone clocked at 1300 mhz and after the update was installed my root was removed and i couldnt access my cpu settings w/o a root. Now my phone is stuck at 1300 mhz and its screwing alot up, frozen screens, tons of force closes, etc please help
You'll have to do the post quoted above. You can't root OTA GB at the moment (if ever).
