The eBook viewer for the iPhone has been updated with a new release, changes are:
Global persistence works! Books.app remembers where you left off in every darn file you read.
Added "unread" indicators for easily telling where you've left off. (Only applies to files, not folders.)
Delete books from the file browser! Swipe your finger across the book (or directory thereof) and watch the magic.
Cover art available! Put a "cover.jpg" or "cover.png" file in the root level of your book's directory, and it will display in the file browser. Get your books from http://manybooks.net and choose iPhone Books.app format, and cover art comes along for free!
Officially released improved copybookdir.sh, provided by Aaron Davies. Thanks, Aaron!
Some HTML files with width tags may display better. This is a horrible kludge--don't expect miracles.
