I don't know that I particularly know anything more than what's out there, but I can try to answer any questions you've got.
Oxicomics creates iPad / iPhone apps that allow you to read comics on your iPhone. All of his apps are free this weekend, so check them out to see how they work. The application allows you to navigate through a comic following a path that simulates reading the comic. Alternately, you can view full pages (better for the large iPad, obviously.) The guy doing it is really friendly and is working hard to make something of it.
