My phone has recently started to ignore WiFi connections, even though it says I'm connected when I go to Settings. It was working at my house earlier, and it has never given me problems, but now it just won't use WiFi at my girlfriend's house. I'm going to head to my house in a little bit, so I'll update the thread with whether or not it works there when I get home. Do you think it's because of a Jailbreak app? I just deleted the only ones I've downloaded recently, like VideoRecorder, Dock, and Cycorder, but that didn't seem to help at all.
