It's actually not all that hard to save the HTML of the Chabad site and to use a HTML viewer on your phone to reconstruct the pages... If you could just save the HTML you could pretty easily to transcribe it into whatever type of HTML viewer you please.. That would be much better than copying and pasting , which would create all type of formatting inconsistencies.
BTW.. I think an Android this would be way easier. I don't like iPhones much and copying files to an iPhone file system is always more of a chore...
