I got the 16GB version as well and did NOT get a email either about the upgrade.
So does your say 5.8 GB for Nook Content + 8 GB free for your own content = 13 GB usable out of the 16 GB?
Also I downloaded the CM7 Root on SD Card Boot option but image is for 4 GB Card. Anyone know how to extend the "image" so I can use like a 16GB Mini SD card and get the "extra storage" as space?
I tried Mini Partition app to extend the FAT32 but still the card only shows 4 GB capacity when I check in Windows Properties.
