I had some trouble with my Droid X, so I ended up SBFing to a stock 2.1, which gave me a bootloader error, so I SBF'ed again to .320. After that, I used the TBH Patches at mydroidworld to update each individual part to .340 via the bootstrapper.
Now, everything is working, and I am completely updated to .340 via all the update.zips.
Will I now be able to receive future OTA updates? I'm worried that since I didn't get .340 through OTA that I won't be able to.
