2. Using public Wi-Fi

The recent explosion of free, public Wi-Fi has been an enormous boon for smart phone users. Since these free access points are available at restaurants, hotels, airports, bookstores, and even retail outlets, you are rarely more than a short trip away from access to a network. The same features that make free Wi-Fi hotspots desirable for consumers make them desirable for hackers, therefore, freedom comes at a price.
