Looks like the SIP-VoIP team over at touchmods.net have been busy.  Last we heard, v.1 of the software that allows the iPod Touch to be used as a VoIP phone via its WiFi connection had launched, and the guys were busy putting together microphone schematics and parts lists.  Now, there’s a pretty healthy list of 25 compatible SIP-based VoIP services - including the popular Gizmo Project and Asterisk - and they’ve just sold out of their first batch of 1200 microphone adaptors, priced at $45 a pop.

If you weren’t lucky enough to get your hands on a first-gen microphone, then you might be interested to hear that the team are kicking about plans for an updated version.  No further details as yet, but they’re expecting to ship them by the end of March.

Is anybody currently using their iPod Touch as a VoIP phone?  Let us know how you’re getting on in the comments
