I wish I'd looked here before buying because now I'm questioning my decision to get an already rooted Nook. It has 2.3.3 and is not on the sd disk which I went back and forth on.. I really thought the disk option was better but a couple reviews said otherwise. Anyways, is there going to be a lot of updating and upgrading necessary? I'm a complete dunce with android and read up a bit about the benefits and capabilites of the rooted Nook so I went for it and got Gingerbread. (Seemed to be good reviews on YouTube and elsewhere.) Since this device is coming with everything on it I won't know the first thing about upgrading it.. will this be a problem? Thanks!!
