You can also directly download books for your iLiad from Feedbooks:
http://www.feedbooks.com
We have a special PDF template for the iLiad that looks wonderful, and today, we'll add Mobipocket support too.
This way you can select between:
- best looking format, but you can't change the size of the font on the device: PDF
- reflowable, but not as good looking: Mobipocket
