With free software from Truphone, iPod touch owners can now use the gadget as a mobile phone to call one another. This does not require a SIM card, but users need a microphone adaptor.
Users can also link up with customers of Truphone's internet telephony service and to users of the Google Talk instant messaging service. Truphone for iPod touch is touted to become a one-stop-shop social hub with the following features promised: making and receiving calls to and from landlines (through a public switched telephone network) at low cost, free IM and calling to Skype and MSN, and free check and set facilities for Twitter and Facebook.
The software uses the iPod touch's Wi-Fi connection to carry calls over the internet to its destination. There is no monthly line rental, no subscription or other hidden charges.
