I am developing an iPad application, and I am trying to figure out the best way to decide if a user can connect to the Internet. If the user has no connectivity, I will load cached data, otherwise I will load new data. I am trying to use Apple's reachability class for this, and I wanted to see if I am doing this correctly. In applicationDidFinishLaunchingWithOptions, I am doing this:

[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name: kReachabilityChangedNotification object: nil];

Reachability hostReach = [[Reachability reachabilityWithHostName: @"www.apple.com"] retain];
[hostReach startNotifer];

Then my reachabilityChanged: looks like this:

- (void)reachabilityChanged:(NSNotification* )note {
    Reachability *curReach = [note object];
    self.internetConnectionStatus = [curReach currentReachabilityStatus];

    if (internetConnectionStatus == NotReachable) {
        [viewController getDataOffline];
    } else {
        if (![[NSUserDefaults standardUserDefaults] objectForKey:kFIRST_LAUNCH]) [viewController getCurrentLocation];
        else [viewController getData];
    }
}

Right now, this is working perfectly for WiFi iPads. I just want to make sure that this will work for 3G iPads. Could you please let me know if I am doing this correctly or not?
