Cult of Mac has confirmed the newest version of Apple’s iPod Touch contains the hardware necessary to enable free or low-cost phone calls over wi-fi.
With 5 wires connected to the Touch headphone jack (instead of 4 on the previous model), the device now supports the external microphone included with some headsets, according to Kyle Wiens of iFixit, who fully dismantled an iPod Touch on Wednesday.
Speculation about the possibility of VoIP (voice over internet protocol – a method for making and receiving voice communication over a connection to the internet, as opposed to the cellular telephone network) on the iPod Touch arose yesterday when the specifications of new Apple headsets with external mics appeared to include support for the iPod Touch in addition to the new iPod Nano and the 120GB iPod Classic.
“”I’m very excited about the possibility of VOIP on [the Touch],”said Wiens. “Now we just need the software.”
The software may already be here, in fact. TruPhone, a venerable innovator in the VoIP field, already has an iPhone application in the AppStore. Apple has said it would not permit applications that run VoIP using cellular networks, but a purely wi-fi-based calling method could pass muster, making the iPod Touch a little less distinguishable from its iPhone sibling.
