Boingo offers more than 4,000 Wi-Fi hotspots in airports, malls, subways, and many other places. And thanks to Google Play, you can use them for free through September with an Android device or a computer (Mac or PC). Funny enough, this offer does not extend to iPhones. It’s funny to me, anyway. But if you find a Boingo hotspot, feel free to use it through September and save some of that precious data.
