I think what he's asking is when creating a blog post, you are faced with choosing between the "HTML" and "Visual" tab. One is the WYSIWYG editor, the other accepts raw HTML. He cannot edit in the Visual editor, which I believe is due to the HTML being rendered and mobile Safari treating it differently than a traditional desktop browser.
However, that said, I just made a blog post using the HTML tab without any issue.
