title: How to verify network connectivity in objective-c
body: <p>I was looking over the Reachability sample project on developer.apple.com and found that it was a large project just to verify you had network connectivity.</p>
  
  <p>First part of the question is "What is the minimum code required to find out if the device can reach a 3G or wifi network?"</p>
  
  <p>And next should this be done inside the appDelegate (on start) or inside the first View Controller that is launched?</p>
  
  <p>Thank you in advance</p>
