Journalists sometimes portray WiFi as the enemy of operator based mobile services.  But if you take a look at this email I got today from AT&T you will see that what we reply at Fon is true.  That mobile operators are concerned about apps that use a lot of data and prefer that traffic to go over WiFi.  Even with HSDPA if people start downloading 300 MB movies for the iPhone network costs are unsustainable.

This is why WiFi has a role to play alongside GSM/3G and other mobile technologies.
