Last week, I posted about TruPhone releasing an iPhone client of their very useful TruPhone VoIP service. For those unfamiliar, TruPhone offers free calls while you’re attached to a Wi-Fi network between phones running TruPhone software; much in the same way Skype-to-Skype calls are free from computer to computer.

Last week, I was with someone who has TruPhone on their iPhone. We conducted a test call between his iPhone and my Nokia E71 and the voice quality was outstanding. Later, we called each other again and had great results.

For anyone who needs dirt cheap calling, or free if you’re both attached to Wi-Fi, be sure to give TruPhone a look.
