First, after the 2.0.1 update installed, my itunes would not recognize my iphone so I restored it to original settings. Then, 2.0.1 was successfully installed and itunes identified my phone but my WIFI is now greyed out and not working. Please advise!
To clarify: It reads "No Wi-Fi" in the Wi-Fi tab of the settings menu. And yes, I'm in an area where I use to receive at least 5 wifi signals.
Same problem here... cannot get back on WiFi--- it show up in available networks, but the iPhone will not connect to it. If I switch Airplane mode on and off, it will then join the Wifi for about 1 sec, then returns to Edge!
I had this same issue with 2.0.0. All of a sudden the place where you select a wifi network was disabled (greyed out) and said No Wifi. There was also no way to turn wifi on or off. I ended up resetting the phone and it came back on. No problems since then.
