To be more specific then,
"AT&T has never officially announced free Wifi to iPhone users."
The point being: the original poster thought AT&T had always included Wifi access as part of iPhone service plans, I was informing him that they had not.

Check. Yeah, I wonder how they got that idea, but with the free WiFi access for ATT's broadband customers, I suppose new iPhone customers just stretched it. It was actually your post however long ago first alerted me we ATT wireless customers would indeed be getting free ATT commercial WiFi.
Also, I read elsewhere (MacWorld) that the attwifi SSID is pointing to the tmobile authentication servers. That's, ah, whack. It's that both access points are still active, T-Mos are weaker but spike signal strength, and if you've ever learned any T-Mo access point and any ATT commercial WiFi access point, your iPhone will keep popping to the strongest signal. When they're about equal it just sort of coin tosses, so you can try to authenticate with your ATT wireless number and that data gets sent to T-Mo's access point and returns a invalid account page. Network technical term for this issue: clusterf***.
Now with a Mac laptop, where you can more easily (pull-down menu) select the SSID you want, no problem. Anyway, mine still works. In fact, I'm not convinced the service is actually down. My buddy at ATT just said both are operating, not specifically free iPhone access has been cut -- I was speculating about why they would cut free B&N access, too, based on description on his description of the walking-on-eggshells deal; I should have made that clear.
What may be happening is that people who think they can't authenticate via their iPhones are actually getting their authentication login captured by T-Mo's SSID. Wouldn't surprise me a bit if those monkeys at T-Mo tweaked their Hotspot network to do a better jobbing of capturing data.
Try deleting "tmobile" out of your list of known SSIDs, but "attwifi". If that fixes and you have the time, call Starbucks, like the regional manager in your area, explain the detail. Then call T-Mo USA corporate, get as high as you can -- ask for the corporate counsel's office -- and ask them just how much they're interested in thousands of complaints pouring into FCC for willful malicious interference on the 2.4GHz spectrum to a subscription wireless service for which you have lawful access. If they're okay with that, ask them how they think FCC will feel about the US operations of the mobile/wireless arm of the German government's socialized telecommunications operations creating this interference with an American company's service, especially after all those nasty things the Germans have said about America over the last few years.
ATTENTION ANY GERMAN NATIONALS READING THIS: I love Germany. Have friends there. One of my three fave nations in the EU. I'm just trying to get something accomplished here. It's Americans running T-Mo USA, not Germans. But the implication is strong and expedient pressure... Well, sometimes the ends justify the means.
