Just stock. I was running aokp 4.1.2 milestone, which I really like, but after flashing a reall bad "super-rom" I just went back to official, but rooted, stock.
It is nova launcher, hd widgets, and file organizer
Mine is probably not worth paying. It's the default 4.1 TouchWiz home screen with the big weather widget. Tried running Apex and Nova, but the launcher fonts were too small and I couldn't find any way to enlarge them.
