I've attached the pdf but the gist is crudely posted below, for those wondering about Apple's iPad recommendations.
And no, I don't have any idea how to get an iTunes connect user account.
PLZ let me know.

Recommendations for Creating EPUB Files
Keep the following points in mind when creating an EPUB file:
Book Content
• All book elements (for example, chapters) that are part of the book text material (that is, the actual book content and not the cover, table of contents, index, and so on) must be identified in the <guide> tag with the type of “text,” with all other guide elements tagged with the appropriate type (“toc,” “title-page,” “epilogue,” “preface,” and so on):
Code:
<guide>
<reference type=”toc” ... />
<reference type=”text” ... />
</guide>
Tagging the book text appropriately is especially essential, as the first guide element tagged as “text” will be shown to customers when they first open a book.
Images
• Images that have any unused or transparent areas should be PNG format with transparency.
• Because there is limited screen real estate, book images are automatically scaled. For this to
correctly work, images should be at the correct intrinsic dimensions when created instead of
hard coding dimensions in the image tag itself.
• To ensure proper viewing of images in content, use the HTML img tag instead of wrapping
images in svg:img.
• The maximum recommended size is about 11 MB of un-encoded image data per chapter.
Fonts
• Do not use explicit fonts, as it creates a bad user experience. Explicit font families should be used sparingly, for example, when trying to achieve an effect such as a handwritten note or for a section that must be in a monospaced font.
• Do not use embedded (downloaded) fonts, as they are currently not supported.
• To ensure that the person reading can make the font bigger or smaller, do not use fixed font sizes; use relative sizes instead.
Adobe Page Template
• The Adobe Page Template XPGT is currently not supported. Use CSS3 instead.
Accessibility
To ensure a good experience for accessibility users, include a valid alt property in image tags.
Line Breaking
To prevent text from being clipped by the bounds of the content area, insert soft hyphens into long words and especially into linked text and headings. Soft hyphens are described in detail here: http://www.w3.org/TR/html401/struct/text.html
Page Mapping
To provide a reading experience similar to printed books, the person reading a book on the iPad should be able to refer to and navigate to a particular page. This is especially useful in a classroom setting when the teacher instructs the students to go to a particular page in a textbook. An NCX (Naviagtion Control file for XML) file lets the reader jump directly to any of the major structural elements of the document (for example, chapter or section) or to a particular page. To provide navigation to a particular page, use the NCX defined pageList. Below is an example:
Code:
<pageList>
<pageTarget id=”p1” type=”normal” value=”1”>
<navLabel><text>1</text></navLabel>
<content src=”content.html#p1”/>
</pageTarget>
<pageTarget id=”p2” type=”normal” value=”2”>
<navLabel><text>2</text></navLabel>
<content src=”content.html#p2”/>
</pageTarget>
</pageList>
Further documentation on the pageList can be found here:
