When Mr. Jobs was showing off the iPhone he used something which was
obviously a web-based view into the same information I'm looking at
in the 'Directory' application. Does anyone know how and where to
enable this ?
That was a hacked up demonstration of how businesses could use the
iPhone's web browser to deliver applications that they needed. It was
not presented as a product.
However, since it was simply a web app that accessed a LDAP store,
and the Directory application is just a front-end on a LDAP store, you
could hack this up in PHP (which has a LDAP module) without too much
work.
