A few notes: by temparilly 'rooting' and putting on a FACTORY .0032 ROM image, the "root" access actually gets overwritten and it becomes a 100% factory imaged tablet. And most importantly, as a result of this, also becomes updatable via future OTA (over-the-air) Toshiba updates.
Also, remember: if you update *beyond* .0032 version, the sd card becomes read-only, apparently due to Toshiba & Android's new restrictions in modern ("honeycomb") versions. I guess it keeps people from sharing apps and pirating copy-protected videos/music, etc.
So.....update beyond .0032 if you want new Andriod bug-fixes, but you'll also being forcing restrictions on what you can do with your sd cards.
A second update: after posting the walkthru earlier, both tablets I received (that arrived having different builds loaded) now work and have identical builds. The tablets both downloaded every new Toshiba OTA updates flawlessly (I don't intend to do any advanced with SD cards, so I prefer to have a more bug-free experience than avoid copy-protections).
The result? Skype is now loaded on both tablets, they call each other flawlessly, and using the dual video cameras, my kids will be able to video-chat with the grand'rents in AZ for Christmas!
Estimated total time investment time to make Thrive updatable: 1 hour (but I'm somewhat tech-savvy). Think of it as 'assembly required'. (Or more accurately: SD card, MSWindows PC and downloading required') if you get shipped a unit with old software build and want it to keep updated.
