What is the "sync" icon next to some Wi-Fi networks? When you go to Menu &gt; Settings &gt; Wireless and network &gt; Wi-Fi Settings there is the list at the bottom which lists all the detected networks in range or remembered. 

The networks in range have the Wi-Fi "signal-strength" icon, and sometimes a lock if it's a secured network. Every now and then though, one or two of the networks will have an icon to the left of the strength, which looks like the "sync" icon from the Accounts screen (the circle with two chasing arrows in it). What does that icon indicate in the context of the Wi-Fi networks?
