title: NetworkReachability in Monotouch returns a false positive
body: <p>I'm trying to test NetworkReachability in the AppDelegate.FinishedLaunching method of my app (invoking on the main thread so I dont hit the 20 sec timeout).</p>
  
  <p>The problem I'm up against is that the test is always returning "false" (i.e. network is not available), even although this is not the case.  I'm running in the iPhone Simulator, and if I let my app run on a bit further, I can access the network with no problem.</p>
  
  <p>I've read elsewhere that there appears to be a known bug in Apple's Reachability code.  I wondered if anyone has come across this issue, and perhaps found a workaround?</p>
  
  <p>Thanks in advance,</p>
  
  <p>Mark</p>
