I just upgraded to the latest firmware & it turned off my bluetooth. When I try to turn it back on, the little wheel just spins & spins & nothing happens. I don't even have the option to re-pair my headset. Now I also note that even though the iPhone logs into my wifi network OK, I can't get any apps to load data from the internet. I get the message in Safari that it can't find the server. Anyone else notice this?
