I was out in public and on the WiFi Networks page in Settings and in the Choose a Network list I saw a weird symbol I'd never seen before. On the left was the network name and then on the right there was the padlock symbol but instead of the concentric arc symbol for the WiFi next to it there was an icon that looked like two interlocked chain-links. I really wish I'd done a screen-grab but unfortunately..... Anybody know what that is? I'm running beta-6 if it matters.
