HTC 2125 / 2100 (Faraday)

I'd love to be able to read e-books on the phone, but from what I can tell, the PDF reader included is pretty weak. For instance, you must choose one of their predefined zoom levels, and there's no way to rotate the display. This means that, for most books, I'd have to constantly scroll right and left for every single line of text.

Anyone know of a way to change that or a good PDF reader that's out there?
