SIP-VoIP for the iPod touch is free, but they're accepting donations. Jailbreakers will enjoy the software, which I assume will be a relatively easy installation. Hopefully Apple doesn't "brick" the iPod touch's of the jailbreakers. Not only won't you be able to play music, but you won't be able to get your VoIP on either. And that my friends would suck twice as badly.
The website even has a cool countdown to the launch that looks very similar to the TV show 24's countdown clock. Speaking of which, when will the Writers Guild strike end? 24 was canceled and I'm none too happy about it.
