Hi, I just bought a laptop, and so far things are great. But, I use my WiFi for internet when I'm at home, but when I go out, I use my iPhone 3G tethering. It works good, but I want to set it so that when I leave my WiFi, it automatically switches to the Bluetooth internet, and vice versa when I come home. Right now it connects to two networks, and that's a waste of my data, especially when my WiFi is 10 x the speed. Thanks in advance
