Remember Marian, the guy who's building a preamped mic
mike for the iPod touch? Today he writes that touch hacker eok has ported Samuel's SvSIP to the iPod. SvSIP uses the SIP protocol to connect to other participants and to allow you to talk over WiFi. I tried porting SIP myself and didn't get very far.
Marian writes that eok has been able to both send and receive calls and promises screen shots as soon as possible.
