I have been recently acquired by an iPhone and has made me go high, nevertheless. The question I have here is, how can I write applications that will actually monitor the processor utilization of an iPhone? How do I go to the deepest level of the architecture and see what app takes how much time to load and how do I minimize it?
With the XCode SDK that you download includes applications to manage and monitor your applications. The application called Instruments is the tool most of us use.
