Auto-Login At Starbucks Without Asking????
I had just done a CLEAN restore of iOS5 and had gone out to eat. I was sitting there eating and noticed my WiFi indicator was on. I thought that was strange and I looked and I was logged into an AT&T WiFi hot spot at the Starbucks across the street. I don't like the fact that they are choosing to log us into a WiFi network automatically with asking.

I'll have to find a AT&T hotspot and give it a try and see what happens. I am assuming you have ask to join networks on am I right. And also you have been to that Starbucks before and used there wifi right. When I went from 4.3.5 to 5.0 info was saved. Wifi and passwords, ringer volumes, etc.

It was a CLEAN restore not a re store from backup. No setting were saved at all.
I have auto join OFF. This is one of the first settings I change after a restore.
AT&T has allowed us to use their wifi hot spots for some time. BUT the iPhone has NEVER logged you on to those network automatically. NEVER.

Had you joined any other AT&T hotspots between the restore and going out to Starbucks? There's an interesting article here about auto-joining AT&T networks and the security risks involved. (Note that the article is from last year; one hopes the security hole has been plugged since then.) From the article:
Typically, an iPhone will look for a specific MAC address--the unique identifier for the router--to verify that the wireless network is a device a user agreed to join previously, according to Kamkar. However, if the iPhone has previously connected to any one of the numerous free AT&T Wi-Fi hot spots (offered at virtually every Starbucks in the U.S., for example) the device will ignore what the MAC address says and simply connect to the network if it has "AT&T Wifi" attached, he said.
"The iPhone joins the network by name with no other form of authentication," he said [emphasis mine].
Kamkar said he made this discovery recently when he was at a Starbucks and disconnected from the AT&T Wi-Fi network.
"I went into the settings to disconnect and the prompt was different from normal," he said. "I went home and had my computer pretend to be an AT&T hot spot just by the name and my iPhone continued to connect to it. I saw one or two other iPhones hop onto the network, too, going through my laptop computer. I could redirect them, steal credentials as they go to Web sites," among other stealth moves, if he had wanted to.
Thanks for that link as I did already know that but many people do not. That is one of the reasons I don't use public wifi and have auto join off. 3G is good enough when I'm out and I'm very security minded (Security Now podcast!).

But I believe it's a different thing because it's a carrier network, not like most wifi networks--in other words, it might be tied to your device on a deeper level than an iOS restore would change. (Maybe via your SIM, or your IMEI, etc.) So it may be that if you had EVER joined an AT&T network, your device will then auto-connect every time until you tell it to forget the network, regardless of whether or not you restored your OS.

Yeah, keep us updated. In the meantime, see if you recall ever joining a different AT&T wifi network--not at that Starbucks, but maybe in a store, or somewhere when you were on the go, etc...that could explain it, especially if it was recently (which would explain why you hadn't seen that behavior at Starbucks before).
OR maybe it is just a foul-up with the GM...
