Hi, I'm a newbie developer and I'm developing a Mac OS X app. One of the functions of the application that I want to accomplish is to access the iPhone file system, the Call History database file specifically. I was searching in Google but I did't find any clues that can help me. I found that I need to use the I/O Kit framework but like I said I'm starting in the world of Development and I don't have any idea how I/O Kit works. I saw a sample code by Apple of using the I/O Kit but really I don't understood it. If someone can bring me a friendly sample code or something that can guide me it should be very helpful! Thanks!
