Already emailed them - I'll post if/when they reply. Just to clarify for other folks:
The iPhone can't download anything, so you can't log into FictionWise to download books for opening in eReader, nor can you synv them via iTunes. The eReader app does let you log into the eReader site to obtain books, but this obviously isn't any use if you're a FictionWise user.
I'm a little miffed at not realising this before I upgraded as the ebook reader app for jailbroken iPhones worked really well...
Update: The readme suggests that eReader will work with FictionWise, but it actually doesn't...
