Why can't this iOS app access the network?

My (Unity) app complains that the my iPod does not have network connectivity while the device has full wi-fi connectivity (as evidenced by every other app, including Safari).

This isn't just one API point - all of them (Facebook, StoreKit, etc) claim that the network is not available.

This message is periodically sent to the console from my app:

<Error>: Could not successfully update network info during initialization.

which may (I think) be coming from CoreTelephony.

Any idea what is causing this? I get it in debug and adhoc builds. I do not have any Restrictions (from Settings) active on the device.

The device is iOS 6 and the base sdk is iOS 5.

I tried set location in simulator and CTTelephonyNetworkInfo initialization in appDelegate.m but not working. I fixed it by define a new class APIAgent.m:

+ (APIAgent *)manager {
    static APIAgent *_manager = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _manager = [[APIAgent alloc] initWithBaseURL:[NSURL URLWithString:API_URL]];
        _manager.responseSerializer = [AFJSONResponseSerializer serializer];
        NSMutableIndexSet* codes = [NSMutableIndexSet indexSetWithIndexesInRange: NSMakeRange(200, 100)];
        [codes addIndex: 400];
        [codes addIndex: 401];
        [codes addIndex: 404];
        [codes addIndex: 409];
        [codes addIndex: 500];
        _manager.responseSerializer.acceptableStatusCodes = codes;
    });

    return _manager;
}

- (id)initWithBaseURL:(NSURL *)url {
    self = [super initWithBaseURL:url];
    if (!self) {
        return nil;
    }

    [[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];

    [self setHeaders];

    return self;
}

- (NSURLSessionDataTask *)GET:(NSString *)URLString parameters:(id)parameters progress:(void (^)(NSProgress *uploadProgress))uploadProgress
                     complete:(void (^)(NSURLSessionDataTask *task, id responseObject, NSError *error))complete {
    return [self GET:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
        if (complete) {
            complete(task, responseObject, nil);
        }
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        if (complete) {
            complete(task, nil, error);
        }
    }];
}

    return [self POST:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {

The "Could not successfully update network info during initialization." log is shown every time you initialize the CTTelephonyNetworkInfo in a device without SIM card, (iPod touch or iPad without 3G).

If it's very annoying, you can just initialize it once and do your network checks against that instance.

Check the developer tools to check if you have accidentally turned on 100% loss internet. It should be in the debug menu.
