1) It sounds like AT&T badly need to invest in some form of packet shaping for their wireless data that prioritizes cell phone data (calls+text+voicemail) over regular traffic.
2) The iPhone should have the option to use Edge for calls, regardless of 3G signal, if there's congestion. Heck I'd probably choose to use Edge all the time, it's so much more reliable in SF.
Re #1: Calls+textmessages are already completely segregated from data.
I'm calling bullshit on this article. HSDPA (3g data) runs on completely different channels than voice calls. Saturation of HSDPA channels will -not- cause calls to be dropped, poor call quality, or delayed text messages.
It will, as you might expect of a well designed system, instead degrade the quality of other data connections.
That's it.
You'll notice that in the article, no one quoted blames the data usage on dropped calls, except one random 'systems administrator' who owns an iphone.
Shrug. All I know is that 3G = calls dropped, 2G = calls solid (irrespective of displayed signal strength). Repeatable on pretty much any Saturday afternoon in downtown SF.

Thanks for playing, NY Times.
