iPhone - Track cellular data usage

Question

Is there a way to track cellular data usage on iPhone ? There are lot of apps which does the same like 'Dataman' and 'DataUsage'

Basically I am looking for a programmatic way to get information stored in Settings -> General -> Usage

Any help will be appreciated.

To check Cellular Network Use this

- (bool) hasCellular {
    struct ifaddrs * addrs;
    const struct ifaddrs * cursor;
    bool found = false;
    if (getifaddrs(&addrs) == 0) {
        cursor = addrs;
        while (cursor != NULL) {
            NSString *name = [NSString stringWithUTF8String:cursor->ifa_name];
                if ([name isEqualToString:@"pdp_ip0"]) 
                    found = true;
            }
            cursor = cursor->ifa_next;
        }
        freeifaddrs(addrs);
    }
    return found;
}
