Since than I made a pretty simple block based Reachability wrapper that strips all the outdated C-like Reachability code, poured into a much more Cocoa form.

Usage like:

[EPPZReachability reachHost:hostNameOrIPaddress
               completition:^(EPPZReachability *reachability)
{
    if (reachability.reachableViaCellular) [self doSomeLightweightStuff];
}];

See Reachability with blocks for everyday use at eppz!blog, or grab it directly from eppz!reachability at GitHub.

It also works with IP addresses, which turned out to be a pretty rare Reachability wrapper feature.

You can use Apple's Reachability code to retrieve this information:

Example:

Reachability *reach = [Reachability reachabilityForLocalWiFi];
[reach startNotifier];

NetworkStatus stat = [reach currentReachabilityStatus];

if(stat & NotReachable) {
   //not reachable
}

if(stat & ReachableViaWiFi) {
   //reachable via wifi
}

if(stat & ReachableViaWWAN) {
   //reachable via wwan
}

Apple's Reachability class will give you this information.
