Turning the iPod Touch into a phone

The MP3 player can be transformed into a mobile phone with the help of a free app from Internet telephone company Truphone. The new app allows users with a Wi-Fi connection to make and receive phone calls via voice over IP with other iPod Touch owners, users of the Google Talk's messaging service, and customers of Truphone's Internet telephone service. The company said it expects to add the ability to handle landline calls.The app creates a virtual keyboard on second-generation iPod Touchs to dial calls and requires the addition of a headset and microphone.However, Apple doesn't appear to be too threatened by Truphone; the application is available for free download at Apple's App Store.
