A couple of years ago I uploaded a large PDF to my now defunct Cubby.com account. I then sent a share link to a friend and he downloaded it to his iPhone, and he still has it. However, because it in iBooks on his phone, there’s now no way for him to get it off, either to his computer, or to Dropbox. Two “Apple Genius” staff told me this yesterday, said that it had something to due with “Copyright Protection” – WTF?
