I'm not sure what version the autoinstaller installs but I've read that it isn't the latest.

0.0.9 is not the same as Gingerbread. NITdroid Gingerbread is the same as Android's Gingerbread, which is newer than 0.0.9.

NITdroid is made to think the eMMC as an SD card. It stores the same information as Android would such as apps (if you want to) and some settings.

EDIT: Android stores its eMMC data in a folder called "Android" and mine has album thumbnails and video and image thumbnails.
