ebook reader app advice

[firecat]

So here's what I want.
An ebook reader app.

• It works on both the iPod/iPad and Android smartphone.
• It stores books and bookmarks in the cloud so when I open the book on a different device, it remembers where I was.
• It also stores books and bookmarks locally so I don't need to have wireless access to use it.
• It lets me upload and store DRMed and non-DRMed epub format books.

Here's where my research has gotten me so far. These apps meet all the criteria except the one listed.

• Bluefire: Doesn't store bookmark data online.
• Google Books, Nook: Can't upload your own books, as far as I know.
• Kobo: Stores bookmark data online for books you get through its store, but not for books you upload.
• Kindle: Doesn't support epub.

Do you know any apps that fit all the criteria?
