10-4. Just as an FYI, there has been a lot of progress on the Android version in the last couple of months. I think, technically, to get the latest, which is a 2.0 version, you have to subscribe to the Android-mobile Beta.
If you want to do that, go to the following link and then click the link there (near the top) to "opt-in" to the beta.

Thanks for that. I'll give it a try when I get a chance.
