Here's a double-whammy for Apple's buzz-generating smartphone and limited-functionality PDA. I'm not really sure how it works, but some hackers have managed to make the iPod Touch run some communications protocol called SIP. Apparently getting SIP to run on a device makes VoIP possible, and apparently this iPod Touch procedure is doable on the iPhone. This is honestly beyond the limits of my comprehension, as some low-level coding and modifications are necessary. Interested parties may check out the TUAW post on the subject. And to anyone who can explain things in layman's terms, feel free to leave a comment.

Thanks to Gadgets on the Go for the heads-up.
