I rebooted my PB yesterday after leaving the hospital. I noticed this red asterisk on the wifi Icon in the status bar. Never seen this before. I swiped down to see if there were any indication on the wifi page, nothing there, did a couple of searches and coldn'nt find it.
So I figured I'd try you guys. Everything works ok, it's just been bugging me :) and after getting a hernia re-repaired it's not taking very much to do that :D
Here's a screenshot (i hope)
