could not select proper transport descriptor
 

Hi all,

I have developed a small Blackberry app for OS version 6.0 and 7.0. This app used salesforce Oauth authentication. This app works fine for OS 6 and 7.

Now when i downgrade the app to OS 5.0 it gives me following error while connecting to salesforce login screen

"could not select proper transport descriptor"


can anyone help me?

Thanks
