I "upgraded" on Thursday. Got the same thing as the screenshot above shows. Figured out how to downgrade to 5.1.1. Did that and got "Wifi not available" where the Off label is. Prior to doing this I tried every remedy suggested, Took it back to Verizon. They upgraded to 6, toggle greyed out. He called Apple. They said they are aware of the issue and to try turning it off in a couple of hours and then back on again - yeah right. Told him I'd try it but if it wasn't working I was coming back for a new phone. The whole thing is ridiculous. At least tell us that they're working on the issue - communication is key and we get none. I'm ready to go back to my dumb phone. This is a pretty common issue on the apple boards. Anyone else here having this issue? Any thoughts to what a resolution might be/what apple is going to do?
