Hi Sandy,
We are looking into this. We had a preliminary solution but it was junk (my opinion) and we pulled it from the 1.0 release. For the short term we added a javascript hook to a message on orientation change to landscape that presents a simple alert dialog stating go back to portrait… not too great but better than nothing.
I’m talking to our dev team now about how to implement a real orientation lock, not a post orientation warning
