The latest release has added "the effective working screenrect" which 
gives you the useable dimensions of the screen when the keyboard is 
showing. The second item in the rect would be the top of the keyboard.

Apps will always quit, the engine doesn't yet support suspend. To return 
to where the user left off, trap the shutdown message and save the 
current state of the app to a file on disk. On preOpenStack, restore it.

The last time I checked, MobGUI was fully functional even if 
unregistered, but on a device or in a simulator it showed a dialog when 
the app launched that said it was an unlicensed version. If you aren't 
seeing anything at all, there might be a problem with the stack or the 
scripts.
