ReachabilitySample with breakpoints

I've been toying around with the Reachability sample<https://github.com/xamarin/monotouch-samples/tree/master/ReachabilitySample>; in an attempt to get an event I can subscribe to when reachability changes (toggle of network connectivity).

From what I can tell, this example is supposed to raise the OnChange event because they're running the NetworkReachability.SetCallBack() and .Schedule() methods. I'm not catching the event at all when I push the app to my phone and turn on airplane mode.

I guess this is somewhat a two-part question:

1. How can I wire up a "ReachabilityChanged" event to fire since this example doesn't [seem to] work?
2. What's the best way to force the "ReachabilityChanged" event to fire on a simulator? (Should deploy to device and turn on Airplane mode cause the event to fire?)

1. Add this to the FinishedLaunching method:

Reachability.ReachabilityChanged += (object sender, EventArgs e) =>  { UpdateStatus (); };

you'll also need to add a "tableView.ReloadData ();" at the end of "UpdateStatus ();" for the UI to update after the changes.

2. You need to turn internet access off on the machine itself. Exactly how depends on your network configuration.

I didn't realize this was using our own monotouch-samples/ReachabilitySample.

I've now fixed the sample.
