The Barnes & Noble Nook just received a software update that brings the firmware version up to 1.1.  Basically, reboot your Nook to get the download to start or you can manually install it. Since the Nook has already been rooted, it's a little surprising that 1.1 didn't break root access, we guess the cat and mouse game has yet to start. According to nookdevs, it is safe to update your Nook to 1.1, you'll still have root access and still can root the Nook at 1.1.

Engadget says that the Nook is faster and basically improved all around. Page turning, the navigation screen, and entire experience is speedier. After using the Nook, the one thing that disappointed us was the speed, hopefully 1.1 really does fix that.
