That was my question after watching the video as well... I was surprised he didn't try doing a tcpdump or something to see what (if anything) was actually being transmitted off the phone with each of those debug messages, though I don't know if that's possible to do without rooting it. Maybe it would be possible to get the Carrier IQ apps running on a rooted device to test this?

You don't need to do tcpdump on the device itself, associating it with your wifi access point and running tcpdump there filtering on client ip would yield the same result.

I'm surprised he didn't do that too, would love to try it myself, can't for a week or so though, someone will have done it by then.

Hah, that's a better idea. Unless it only transfers the data through a cell data connection (I don't really see any good reason why that would be the case but it's a remote possibility).

the article states this is not the case - it also uses wifi.
