This can not be possible for me. I just got a Verizon 4s on Sunday after waiting forever to get an iphone. 16g model A1387. Has not been dropped or wet. In fact, I hardly even touch it for fear of getting fingerprints on since I don't have my case yet. I have an ipod touch so I'm not new to apple products.
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.
