hi, the rotation locker ( from xda - forum) might work.

works on my android phone. i'm thinking about getting the sony t1 and it would be really interesting if the repligo reader functions properly in landscape mode.
in case it worked it would be nice if you could write something about the refresh rates while scrolling (zooming, etc) through pdfs and annotating those.
thanks in advance!
