title: Reading call history in iPhone OS
body: <p>I'm doing some research on the feasibility of an iPhone application, and can't find any indication in Apple's documentation that an iPhone app can read the call history of the phone, specifically the number/address book entry called, when, and the duration.</p>
  
  <p>Does anyone know if this is possible, and how?</p>
  
  <p>Note: The purpose is to remove the need for the user to perform this data-entry themselves. The application is for recording interactions with customer service centers.</p>
