Good simple summary, but I don't believe that will work for those that forced the OTA last week, or for those that are running FRG22. But maybe that was your intent in the first place anyway, so I'm not criticizing.
This does indeed work for people who installed last week's OTA.
From the OP: As a side note this new full update will not work once you use last weeks OTA update. The script specifically looks at what you currently have running.
