wifi on iphone simulator

After disabling your network connection, the icon is still present showing it as enabled, but the connection is of course dead. If you are using the Reachability class or just attempting to ping a URL to verify a connection, the simulator will respond the same way a device with disabled Wifi would, which makes testing on the simulator under these conditions pretty accurate.
