Jailbroken iPhone: Application Delegate Methods not Found on Device

Question

Hi all,

In the simulator, I don't have this problem but when I run the app on my device applicationDidBecomeActive and applicationWillTerminate aren't called. Is it because I'm jailbroken and running backgrounder etc? Here's the gdb log from Xcode:

This...

warning: UUID mismatch detected with the loaded library - on disk is:
 /Volumes/Xcode/MyAppName/build/Debug-iphoneos/MyAppName.app/MyAppName

...is the kiss of death for a jailbreak project. It means that none of your paths, which are built from the UUID, will resolve. On the device, the loader literally cannot find the paths to the necessary files.

There's supposed to be something in the jailbreak tool chain to compensate for this but I don't remember what it is.
