I've had my iPhone 3GS for about 2 months, and all of a sudden it stopped picking up wifi and 3G, (at my house) when I go into my setting app, and then wifi, it picks up that there is a network available, so I choose it, and the check mark appears, the bars that normally appear at the top of the phone do not show up, and I have no wifi, but from time to time, the wifi bars do appear and disappear, but still do not receive a "true" wifi connection. same with 3G, it all works when im in town, or at someone else's house. I have restarted everything, and I have restored my iPhone. Not sure the problem.
