Reading academic papers on the iPhone I frequently want to read academic papers while on the go. They're usually in PDF format, so I sync them to my iPhone with iBooks.

The problem is that most of the papers I want to read are in a two-column format that's extremely difficult to read on the phone's screen - I have to zoom in on a column, scroll down, then scroll up to the top of the next column and repeat.

Is there any software that will "flatten" out the PDF? I love Instapaper for web-based information; something that could turn a two-column PDF into a long stream of text and images would be great.
Goodreader for the iphone extracts text and images and fits them to your iphone screen and can be customized to your liking.
