I just thought I'd mention, MobiPocket is listed on the ePub Wiki as available software for ePub reading. Maybe it doesn't really support it, I don't know. I have no ePub books.
Also they posted this over a year ago!
Mobipocket Desktop supports ePub and to be released on the iPhone

Readers,
ePub Blog
At this year’s IDPF Digital Book 2008 conference,
we had confirmation from Mobipocket president and CEO, Martin Görner, that
Mobipocket Reader Desktop 6.2 is able to import ePub files, with the next version being able to
create ePub files. At present the reader does not read ePub files natively, it converts them to the MOBI format before transferring to your device.
One minor issue is that the reader does not create a TOC (Table of Contents) from the toc.nsx file contained in the ePub document. Let’s hope they don’t take too long to fix this.
Also in his talk, Görner announced that by the end of the year, the Mobipocket Reader will be available on the iPhone. I guess with the recent release of the iPhone SDK this should be no surprise, but great news nonetheless.
Acceptance of ePub is growing from strength to strength, with one more reader adding support for the format. Mobipocket Reader now covers many devices including the iPhone (end of 200
, Blackberry, Windows Mobile, PDA and a number of dedicated ePaper devices. Once the reader is updated across these devices, ePub support will be opened up to a whole new batch of users.
