Use the real Web instead just a web optimized for mobile.
And use it WYSIWYG-style with touches, panning, zooming, clicking.

GUI in the first iPhone was understandable even to "common people" and there was not N level hierarchies of menuitems to navigate to do something.

Before iPhone there was Blackberry which already was a winner for non technical people. Using email in BB was alot easier than with phones Nokia used to ship (except communicator which was too expensive)
