title: Memory Leak from Foundation & CFNetwork Library
body: <p>I am using instruments to resolve memory leak issues for an app in iPhone. I just wanted to know if I have to resolve the leaks coming from Foundation and CFNetwork Libraries. Specifically, the leaks are from:<br>
  1. NSCFString<br>
  2. NSConcreteData<br>
  3. General Block-3584<br>
  Since they do not directly point to the code that I have written, how should I resolve them, if I have to?</p>
  
  <p>Thanks.</p>
