Did You Know Your iPod Touch is a Phone?

With the arrival, finally, of Apple’s Premium earphones with remote and mic, you can now use your iPod Touch as a telephone through the magic of free software from the VoIP pioneers at TruPhone.

Actually, that’s somewhat inaccurate. You’ve been able to partake of TruPhone’s magic previously using a microphone adapter that plugs into the dock connector, or a headset with built-in mic like the one that ships with iPhones, but now that Apple’s new headsets are on the way, TruPhone’s app seems much more interesting.

Once you’ve installed the software, you can make free calls–no matter where you are in the world–to other iPod touch owners, to customers of Truphone’s Internet telephony service and to users of Google Talk instant messaging service. Support for low cost calling to landlines (PSTN) is on the way, according to company reps, as is support for calling and instant messaging to Skype and MSN (free) and free check and set facilities for both Twitter and Facebook.

The software uses the iPod touch’s Wi-Fi connection to carry VoIP calls over the Internet to its destination. There is no monthly line rental, no subscription or other hidden charges, but it should be noted calls are not handed off to the cellular network if you move beyond or lose your WiFi connection.

Still, when you bought that iPod Touch, I bet you didn’t think you were getting a telephone, too.
