When I got my tablet last year, I used these instructions from Cdesja5 [she helped me with my Sony T1 too and I think this post was from that forum or in the tablet forum, not sure, just copied the link down with my instructions] This is how I sync my Samsung Tablet with my Calibre library and I use Aldiko to read on it. Not sure if this is helpful to anyone here or not but thought I'd post it.
ETA: Remember I am NOT a techie person so just posted this because it was easy and worked for me, not sure if this is even along the same lines as what you guys are talking about!
