title: Duplicate Symbol SBJSON on iOS Facebook SDK V 3.0
body: <p>In the current project, I used SBJSON everywhere and got it working fine with the previous version of iOS Facebook SDK since SBJSON was included in Facebook SDK.</p>
  
  <p>I just upgraded to iOS Facebook SDK version 3.0 and having problem with SBJSON.</p>
  
  <p>The first thing it complaint was about NOT finding SBJSON header file. So I thought, I could manually include the SBJSON lib into the project.</p>
  
  <p>After I did that, then the compiler complaint that the SBJSON symbol was duplicated with the Facebook SDK.</p>
  
  <p>I could not find the SBJSON.h anywhere in FB SDK headers.</p>
  
  <p>So at the end, I went into a loop of problems.</p>
  
  <p>Does anyone know how to solve this issue? 
  The worst case could be that I have to switch to use other JSON library for iOS.</p>
  
  <p><strong>Note:</strong>  They are using framework for Facebook SDK, not the source code library like before</p>
  
  <p>Cheers</p>
