title: Can an iPhone OS app do a search of the device's filesystem?
body: <p>Can I do a search of the iPhone filesystem from within an application? I need to search an iPhone OS device and return a list of all apps installed on an iPhone OS device. I am fairly aware of Apple's restrictions and rules concerning what apps can and mostly cannot do outside of the sandbox -- and know that aside from the <em>Photo Album</em> an <em>Address Book</em> (via specified classes) an application is not allowed to access much of anything outside of its home directory (sandbox) for security. But the boundaries are fuzzy. </p>
  
  <p>Anyway, back to the question: Can UISearchBarDelegate (or any other class/protocol) allow me to search the iPhone device?</p>
