Upgrade to iPhone SDK 3.0 Causing UIKit Problems

I have an existing project that I was working on, and I recently decided to update my iPhone SDK and updated to the latest 3.0 SDK. I update my SDK and go to open my existing project. Sure enough, there are some problems including some certificate problems and so on. Anyway, google and I were able to solve most of them, but I haven't had any luck on what I hope to be the last of my problems. When running my program in the simulator, I now get dyld: Library not loaded: /System/Library/Frameworks/UIKit.framework/UIKit Referenced from: /Developer/iGameLib/iGameLib/build/Debug-iphonesimulator/iGameLib.app/iGameLib Reason: image not found Now, I discovered the UIKit has moved to /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0sdk/ System/Library/FrameWorks/UIKit and I have updated my target and project settings to point to that new framework location, but still when I build it, no luck. I have also tried clearing out the simulator's applications and settings, still no luck. The referencing .app is cleared when I run the "clean" menuitem, I have confirmed this, so clearly something in my project settings are still pointing to use the old UIKit location. Where should I be looking? I've gone as far as I can to help myself but I'm afraid I'm at a loss here. I don't see it under the target settings, or the project settings, or the plist, or any of the other files within my project.
