Dumping frameworks for iPhone 3.0 not working?

Question

Hey I need some extra capabilities for my program and I would like to use some Undocumented APIs for my iPhone program. I downloaded: DumpFrameworks as Dumpframeworks.pl and class-dump from : http://ericasadun.com/HeaderDumpKit/

I put DumpFrameworks.pl in Downloads and class-dump file in /usr/local/bin

in the terminal I run:

$perl DumpFrameworks.pl

and some warnings and errors appeared:

Framework: Accelerate
2009-09-30 08:39:58.776 class-dump[466:903] Warning: This file does not contain any Objective-C runtime information.
Framework: ApplicationServices
2009-09-30 08:40:00.443 class-dump[473:903] Couldn't read file: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/ApplicationServices.framework/ApplicationServices
2009-09-30 08:40:00.449 class-dump[473:903] Couldn't read file: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/ApplicationServices.framework/ApplicationServices
class-dump: Input file (/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/ApplicationServices.framework/ApplicationServices) is neither a Mach-O file nor a fat archive. 
... etc (above warnings are very common when I run the perl script)

***But the most important thing, The script seems to fail in the end.

I got***

(after several warnings like above)
Framework: WebKit
    2009-09-30 08:40:24.228 class-dump[662:903] caught exception: expected (many things), got 260
    2009-09-30 08:40:24.232 class-dump[662:903] type: ^{WebDocumentLoaderMac=^^?iB^{Frame}{RefPtr<WebCore::MainResourceLoader>="m_ptr"^{MainResourceLoader}}{HashSet<WTF::RefPtr<WebCore::ResourceLoader>,WTF::PtrHash<WTF::RefPtr<WebCore::ResourceLoader> >,WTF::HashTraits<WTF::RefPtr<WebCore::ResourceLoader> > >="m_impl"{HashTable<WTF::RefPtr<WebCore::ResourceLoader>,WTF::RefPtr<WebCore::ResourceLoader>,WTF::IdentityExtractor<WTF::RefPtr<WebCore::ResourceLoader> >,WTF::PtrHash<WTF ... etc (I got many many lines of this kind of code in WebCore framework)

I wonder What I am doing wrong here? Do I need some additional settings?

I am using Mac OS 10.6.1 and would like to dump 3.0 frameworks in first place but my real aim is 3.1 frameworks

Any help would be very appreciated.

From my understanding of undocumented APIs they are there. So in any app I could just call them.

From my understanding of class dumps, they are needed to discover undocumented APIs.

In Sadun's book she says, here's an undocumented-API call this to use it, include this in the header. Then you could use it.

My recommendation is don't use them.
