Hey Raff, can you please hit me back via email / call?
Dynamic XFA forms created in Designer will not work on an iPad. There is no support for XFA within Apple's PDF implementation, and Adobe's Reader does not do XFA forms either. There have been a other threads on this in the designer forum, which is where I will move this thread. I don't believe that Adobe looked at forms as the major usecase for apple mobile; anything that you might be able to do will be limited to PDF forms (designed as page overlays in Acrobat) or possibly some PDF artwork forms in Designer, but those may lose most of their scripting.
Possibly some other folks in Designer can help.
We have a solution that allows you to do most of what you want, including bulding the form, having people fill it out either in Reader (as an XFA-PDF) or on the iPad (as an HTML form).
You design the form once, and it will by styled correctly on the appropriate platform.
