iPhone app behavior normal?

I am testing my app in an iPhone. I am using http://mobile.zoho.com/creator.

The form loads but is very small and I need to expand it to see it everytime. Further, when I tap on a form to add a new record, it opens a new 'window' in the browser and I can't easily navigate back to the main page to select a different form to use or a view.

Is this normal behavior? I hope not. Not user friendly at all.

How can I change this? The app works better with this URL http://creator.zoho.com/mobile but can't support scripts on the client side.
