I just downloaded Fring, a free VoIP app for the iPod Touch. I'm ready to purchase a couple of credits (they're cheap) and try this baby out, but I have no special mic headphones to talk through. I already own a good pair of headphones, so can I get a splitter to give me an extra jack for a mic? If that's not possible, can anybody show me to some cheap (usable) mic + headphones? This is so cool; I can't wait to try it out.
