Just used the process on page 1 to go from unrooted, stock GB to .208. I rooted first, then used OTA Rootkeeper (protect root, temp. unroot, re-root), then put 208 in place via my SD Card. After the eventual reboot, I went back into OTA Root Keeper, did a restore root, and it appeared to work. I believe I currently have kept root, which should be pretty helpful when the official OTA update is ready.
Additionally, all my apps and data migrated perfectly. I did not have to wipe anything on it. Thanks a bunch guys!
