title: IOS Jailbreak How do intercept SMS / Text Messages
body: <p>I'm currently trying to write an application that intercepts text messages and reacts depending on the content of that message. 
  I tried to hook into <code>_receivedMessage:(struct __CKSMSRecord *)message replace:(BOOL)replace</code> method in the CKSMSService class but this seems not do get called at all. </p>
