The following bug is something that started occurring today...
Whenever I try to connect to any WIFI network (routers, mobile hotspots), I can see my iPod tries to connect, but instantly loses connection. When I try to do this manually, it connects but immediately shows a screen with address http://www.apple.com, the title of the screen is "Log In" and the screen contains:
<HTML><HEAD><TITLE>Success</TITLE></HEAD><BODY>Success</BODY></HTML>
The only thing I can do is press Cancel in the right top corner... My ipod runs on iOS version 6.0.1.
