For the benefit of anyone else with the same issue: there actually is one way to run a standard Access application on an iPad besides the browser.
But it still requires internet connectivity and for access to be available via a citrix application gateway that you have available to you. Then you can download the (free) Citrix Reveiver app on your iPad, and work with Access via Citrix. I have designed and deployed two Access databases for use under this scenario and it works pretty darned well. But unless your organisation already has a citrix farm setup, and an IT department to run it, this is unlikely to be as relevant as the browser based solution Pat Hartman has already discussed.
