"The report notes that a similar restriction is likely for any Netflix video streaming on the iPhone."
...but I can stream YouTube and audio (iHeartRadio, Slacker, Pandora, etc, etc) via 3g...
If ATT is scared of video, they need to ban YouTube streaming via 3g. Oh wait...
(I actually think bans are Apple, not ATT. I watched Singbox on my Bold all the time via 3g).
The bans are definitely at&t. Their concern is that the iPhone is a more capable device, with a better screen, that more people have it, and that everyone who has it has a data plan.
All this combines to a lot more bandwidth usage than from Blackberry Bolds.
Quote from at&t:
"Slingbox, which would use large amounts of wireless network capacity, could create congestion and potentially prevent other customers from using the network. The application does not run on our 3G wireless network. Applications like this, which redirect a TV signal to a personal computer, are specifically prohibited under our terms of service. We consider smartphones like the iPhone to be personal computers in that they have the same hardware and software attributes as PCs."
