I for one am disappointed that we do not have access to not even half of the vast library that is on the Bible Support site! The iPad is the best invention since the Lap Top.
Rick's e-sword website has a conversion tool that will convert unlocked modules to ipad format. I have an iPad mini, am new to it, having always used Android or Windows. But with the conversion tool and iFunbox, it's pretty simple to just convert the modules you have for your Windows version of E Sword and convert them yourself. I just read the directions and this post on Bible Support was also a great help.
