Curious about this. I went to two AT&T Hotspots today (The Coffee Bean) in Pasadena, CA. My iPhone asked if I wanted to join the AT&T WiFi network and I said yes. It allowed me to access it without a password and surf the net. It was definitely their WiFi and not EDGE. The speed was crazy fast and I had a full WiFi icon that remained a WiFi icon (never switched back to EDGE). The iPhone WiFi pop-up had a lock beside the AT&T WiFi network, but I selected it with no prompt for a password. Anyone else experienced this?
