I am doing a course in Literature that required a book. I didn't want to buy a hard copy since i was going to have to annotate it. So i bought it from iTunes, thinking that i could convert it into a pdf. Then I realised it was protected by Apple FairPlay DRM. So i downloaded Requiem 3.3.5 to strip the DRM, but it said that I needed a newer version of Requiem as the ePub iBook was a new version. So I downloaded Requiem 4.1. But in this version it doesn't detect ANY DRMs. I thought Requiem 4.0 would work, but this version didn't detect any DRMs either. I am really confused.
