I bought ebup book from ebooks.com
http://www.ebooks.com/
I want to read it on iPhone using iBook
So I tried to convert it using Calibre but error message appear
"You must first remove the DRM using third party tools."
I can not make out what third party I'm supposed to use.
Do you recommend some tool?
I do not want it to be converted another type of file.
I want read it as epub.
thanks!
