It's on, it's off, it's on again: Access to AT&T hotspots is back on again, at least in the fine print, as the company now includes the statement that all iPhone plans in the U.S. include "access to AT&T's more than 17,000 Wi-Fi hotspots, including Starbucks." (Click the Plans tab at top to see that text.)

AT&T appeared to have flipped a switch several days ago on its "attwifi" SSID that has appeared alongside T-Mobile's during this several-month transition at Starbucks from one operator to another. iPhone users were presented with a custom login screen that prompted them for their phone number to obtain free access. That gateway page disappeared a few days. I haven't tested if it's back, but at least AT&T has, at long last, made the connection that its iPhone customers might enjoy the same free access to hotspots as its 7m fiber and qualifying DSL customers.
