I couldn't get on with version 2.0, and it took me ages to find the 1.9 again.
Blackberry say the 1.9 no longer exists....cos I contacted them and asked....but is does say quite plainly on their site that the older version for earlier OSs is there.....and it isn't.
Anyway, try the link on that post.
