AT&T Announces 3.0 Users No Longer Need To Sign In To AT&T Wi-Fi Hotspots

AT&T revealed a minor but pleasant surprise coming with the iPhone OS 3.0 software. They announced that all 20,000+ of their Wi-Fi hotspots in the U.S. will support auto-authentication, letting them skip the authentication process. That means that as of today, instead of having to sign in, your iPhone will automatically switch from 3G to Wi-Fi when you’re at an AT&T hotspot. The hotspots are free to use on your iPhone for anyone with an unlimited data plan.
