Edit: There are now screenshots of the app in action; not exactly pretty, perhaps, but great functionality! 

We’ve been following the development of Marian’s discrete iPod Touch microphone accessory for a while now, crossing our fingers that as the hardware becomes available so will a VoIP client to make the most of it, and the latest is that a port of the Nintendo DS app SvSIP has been suitably fettled for the Apple PMP.  So far there’s no screenshot or compilation, but both are supposed to be on their way from coder eok who is responsible for the port.

This would mean that the iPod Touch - with both microphone attachment and software - could be used as a handset to access a SIP-compatible VoIP service via WiFi.  It potentially answers the main criticism aimed at the PMP when compared to its older brother the iPhone: that it cannot make voice calls.

Edit: In an update, Marian has explained that currently no voice data has been communicated - they’ve just signalled calls in and out of the SIP server.
