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 *Photo Album* an *Address Book* (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. 

Anyway, back to the question: Can UISearchBarDelegate (or any other class/protocol) allow me to search the iPhone device?
