How to check iphone network connection

Hi,

i would like to check on iphone whether there is any network connection. I am using iPhoneNetworkReachability.ReachableViaWifiNetwork. Tho i dont know whether this acounts only for wifi or any other type of network connection. I tried to find some additional info on this in reference manual, but there is nothing about this.

So can please anyone help me, how to check for online connection on iphone for all types of connection ?

Thanks a lot.

Luke
