If you're an iPod Touch user, you need not be incommunicado. If you're in the vicinity of a Wi-Fi hotspot, you can use your device to make calls, including calls to landline and cell phones. In this review in the Wall Street Journal, Walt Mossberg tests three apps — all FREE — that let you make calls without needing $70/month phone service like your iPhone brethren. In his comparison of the three apps, Mossberg finds that Skype has better call quality than Fring or Truphone.
