When I first started my iPhone, it connected to the WiFi network. When I left my house for the first time it automatically used edge, which is good. The only problem now is that now it won't go back to WiFi. I can't even access the WiFi settings, I jsut get a "No WiFi" message that is un-tappable. I am not using an unlocked iPhone and I restored it several times and it still won't work. Any advice is appreciated. Here is a link to a video of the problem on youtube: http://www.youtube.com/watch?v=vpUploqr1ls
