Monitor iphone application api calls

Question

I was wondering if there is any way to monitor 3rd party iphone applications' api calls? For instance if application access address book is there a way to monitor that or intercept call? I understand it may not be possible to do so without jail-breaking, but is even possibility after having jail broken the phone?

Thanks!

Answer 1

No there isn't.

You can howerver, starting in iOS4, see what apps have used location services (you can find this in settings.app).

Answer 2

If you jailbreak the phone, you can replace the frameworks and add any required logging. It's going to be pretty difficult to do, though.
