Walt Mossberg talks about broadband in the US, the argument between streaming and downloading, and… a 3G iPhone… in 60 days! (about 6:53 into the video).
Walt Mossberg is often one of the journalists that Apple gives a review unit to first so he may know for sure, but on the other hand it almost sounds like he is just saying 60 days to prove a point, that the iPhone will be 3G in no time, not necessarily in 60 days, but soon.
