Hey . I recently jailbroke my Iphone 3g with redsn0w to firmware 4.2.1 . After installing the firmware , everything was working fine epect for my Wifi . Whenever I go to the wifi settings it shows "Connections" with the spinning circle next to it , but no Wifi conenctions appear , even when I place my iphone directly next to my wireless router . My laptop picks up the wifi perfectly as well . I have tried everything from resetting the network settings to going into airplane mode and restarting my iphone . Anyone else has this problem and knows how to fix it ? All help is appreciated
