True! but the software should not name the tablet with the OS version to begin with. And we have to go to bluetooth setting to change the hostname (weird heh?) It is kind of confusing when the OS has ability to update to a newer version! It should just name the tablet simply like "N8x0" instead. My problem was I did not update OS in flash but it was shown the same version as the OS in the mmc where the lasted OS was updated.

Apparently, the version number was updated somewhere in flash and picked up then displayed by both OS versions.
