Skype iPod Touch

You’re now able to make free phone calls via Internet on Apple’s iPhone using a new Skype application. But if you own a second-generation iPod touch, you can also make free calls, even though the Touch technically isn’t a phone. Skype’s iPhone app will function with any second-gen touch as long as you use a set of headphones with a microphone built into the earphone cord. (Unfortunately, the original Touch has no audio-in capability.) Other than that, you’ll need just a Wi-Fi network. The application allows you to make free calls to other Skype users and paid calls to non-Skype users. i like Skype’s ubiquity and audio quality, but it has competitors; if you want to experiment, you might try Truphone (www.truphone.com) instead.
