I have an idea on how to root .621 droid x phones.
I have read that the people who have root used Voodoo OTA Rootkeeper,
used it to save their root before the Verizon upgrade,
and after the upgrade did a OTA Rootkeeper restore of their root.
Now, I imagine that OTA Rootkeeper is saving this information on the SD card?
If so, then someone who saved their root files using OTA Rootkeeper
can transfer the saved folder from their SD card to a computer, zip it up, share it with everyone.
Then everyone can install OTA Rootkeeper and do a root restore function.
However, if OTA Rootkeeper does not store the backup root on the SD card, then
this idea will not work.
