Naz, I think it would probably be more related to keeping track of your questions when you're out and about rather than the Asking/Answering aspect of the site (although, this would need to be included obviously). It would probably default to something similar to the "My Profile" page.
I love answerbank and I love my iPhone, most sites now are either set up for mobile or have an app, even my bank has an app now, would be cool to have AB on here as well
