I havent been able to connect to any WiFi signals... not at home, not at a friends. So I removed MyWi and I still had no luck, so I reinstalled it and then my WiFi started to work again. But shortly after it crapped out again. The wierd thing is... When I turn MyWi on, I can connect my 3GS to MyWi using WiFi. Has anyone else had any problems with their WiFi?
