IOS 5 wifi bug
I have just installed ios5 gm to my iphone4. When I try to connect a WPA2 enterprise wifi, after the connecton is established, it is OK. But after a while, if you switch your iphone to 3G and close wifi. Next time, when you enable wifi, the WPA2 enterprise wifi network will never be connected unless you reset your network settings.
iPhone 4, Other OS, ios5 gm
