There seems to be a shortage of information about this online, I hope this can help someone.

First copy Reachability.m/.h into your project and include #include "Reachability.h" into your class.

	Reachability *reach = [[Reachability alloc]init];
	if (reach.internetConnectionStatus == NotReachable) {
		NSLog(@"No Connection Found");
	} else if (reach.internetConnectionStatus == ReachableViaCarrierDataNetwork) {
		NSLog(@"3G or Edge");
	} else if (reach.internetConnectionStatus == ReachableViaWiFiNetwork) {
		NSLog(@"Wifi Connection");
	}
	[reach release];

This code may not be the best way to accomplish this, but it appears to be the most simple approach.
